* Classes to support module descriptors and creating configurations of modules
* by means of resolution and service binding.
*
* <h2><a id="resolution">Resolution</a></h2>
*
* <p> Resolution is the process of computing the transitive closure of a set
* of root modules over a set of observable modules by resolving the
* dependences expressed by {@link
* java.lang.module.ModuleDescriptor.Requires requires} clauses.
* The <em>dependence graph</em> is augmented with edges that take account of
* implicitly declared dependences ({@code requires transitive}) to create a
* <em>readability graph</em>. The result of resolution is a {@link
* java.lang.module.Configuration Configuration} that encapsulates the
* readability graph. </p>
*
* <p> As an example, suppose we have the following observable modules: </p>
* <pre> {@code
* module m1 { requires m2; }
* module m2 { requires transitive m3; }
* module m3 { }
* module m4 { }
* } </pre>
*
* <p> If the module {@code m1} is resolved then the resulting configuration
* contains three modules ({@code m1}, {@code m2}, {@code m3}). The edges in
* its readability graph are: </p>
* <pre> {@code
* m1 --> m2 (meaning m1 reads m2)
* m1 --> m3
* m2 --> m3
* } </pre>
*
* <p> Resolution is an additive process. When computing the transitive closure
* then the dependence relation may include dependences on modules in {@link
* java.lang.module.Configuration#parents() parent} configurations. The result
* is a <em>relative configuration</em> that is relative to one or more parent
* configurations and where the readability graph may have edges from modules
* in the configuration to modules in parent configurations. </p>
*
* <p> As an example, suppose we have the following observable modules: </p>
* <pre> {@code
* module m1 { requires m2; requires java.xml; }
* module m2 { }
* } </pre>
*
* <p> If module {@code m1} is resolved with the configuration for the {@link
* java.lang.ModuleLayer#boot() boot} layer as the parent then the resulting
* configuration contains two modules ({@code m1}, {@code m2}). The edges in
* its readability graph are:
* <pre> {@code
* m1 --> m2
* m1 --> java.xml
* } </pre>
* where module {@code java.xml} is in the parent configuration. For
* simplicity, this example omits the implicitly declared dependence on the
* {@code java.base} module.
*
* <p> Requires clauses that are "{@code requires static}" express an optional
* dependence (except at compile-time). If a module declares that it
* "{@code requires static M}" then resolution does not search the observable
* modules for "{@code M}". However, if "{@code M}" is resolved (because resolution
* resolves a module that requires "{@code M}" without the {@link
* java.lang.module.ModuleDescriptor.Requires.Modifier#STATIC static} modifier)
* then the readability graph will contain read edges for each module that
* "{@code requires static M}". </p>
*
* <p> {@link java.lang.module.ModuleDescriptor#isAutomatic() Automatic} modules
* receive special treatment during resolution. Each automatic module is resolved
* as if it "{@code requires transitive}" all observable automatic modules and
* all automatic modules in the parent configurations. Each automatic module is
* resolved so that it reads all other modules in the resulting configuration and
* all modules in parent configurations. </p>
*
* <h2><a id="servicebinding">Service binding</a></h2>
*
* <p> Service binding is the process of augmenting a graph of resolved modules
* from the set of observable modules induced by the service-use dependence
* ({@code uses} and {@code provides} clauses). Any module that was not
* previously in the graph requires resolution to compute its transitive
* closure. Service binding is an iterative process in that adding a module
* that satisfies some service-use dependence may introduce new service-use
* dependences. </p>
*
* <p> Suppose we have the following observable modules: </p>
* <pre> {@code
* module m1 { exports p; uses p.S; }
* module m2 { requires m1; provides p.S with p2.S2; }
* module m3 { requires m1; requires m4; provides p.S with p3.S3; }
* module m4 { }
* } </pre>
*
* <p> If the module {@code m1} is resolved then the resulting graph of modules
* has one module ({@code m1}). If the graph is augmented with modules induced
* by the service-use dependence relation then the configuration will contain
* four modules ({@code m1}, {@code m2}, {@code m3}, {@code m4}). The edges in
* its readability graph are: </p>
* <pre> {@code
* m2 --> m1
* m3 --> m1
* m3 --> m4
* } </pre>
* <p> The edges in the conceptual service-use graph are: </p>
* <pre> {@code
* m1 --> m2 (meaning m1 uses a service that is provided by m2)
* m1 --> m3
* } </pre>
*
* <h2>General Exceptions</h2>
*
* <p> Unless otherwise noted, passing a {@code null} argument to a constructor
* or method of any class or interface in this package will cause a {@link
* java.lang.NullPointerException NullPointerException} to be thrown. Additionally,
* invoking a method with an array or collection containing a {@code null} element
* will cause a {@code NullPointerException}, unless otherwise specified. </p>
*
*
* <h1><a id="resolution">Resolution</a></h1>
*
* <p> Resolution is the process of computing how modules depend on each other.
* The process occurs at compile time and run time. </p>
*
* <p> Resolution is a two-step process. The first step recursively enumerates
* the 'requires' directives of a set of root modules. If all the enumerated
* modules are observable, then the second step computes their readability graph.
* The readability graph embodies how modules depend on each other, which in
* turn controls access across module boundaries. </p>
*
* <h2> Step 1: Recursive enumeration </h2>
*
* <p> Recursive enumeration takes a set of module names, looks up each of their
* module declarations, and for each module declaration, recursively enumerates:
*
* <ul>
* <li> <p> the module names given by the 'requires' directives with the
* 'transitive' modifier, and </p></li>
* <li> <p> at the discretion of the host system, the module names given by
* the 'requires' directives without the 'transitive' modifier. </p></li>
* </ul>
*
* <p> Module declarations are looked up in a set of observable modules. The set
* of observable modules is determined in an implementation specific manner. The
* set of observable modules may include modules with explicit declarations
* (that is, with a {@code module-info.java} source file or {@code module-info.class}
* file) and modules with implicit declarations (that is,
* <a href="ModuleFinder.html#automatic-modules">automatic modules</a>).
* Because an automatic module has no explicit module declaration, it has no
* 'requires' directives of its own, although its name may be given by a
* 'requires' directive of an explicit module declaration. </p>
* <p> The set of root modules, whose names are the initial input to this
* algorithm, is determined in an implementation specific manner. The set of
* root modules may include automatic modules. </p>
*
* <p> If at least one automatic module is enumerated by this algorithm, then
* every observable automatic module must be enumerated, regardless of whether
* any of their names are given by 'requires' directives of explicit module
* declarations. </p>
*
* <p> If any of the following conditions occur, then resolution fails:
* <ul>
* <li><p> Any root module is not observable. </p></li>
* <li><p> Any module whose name is given by a 'requires' directive with the
* 'transitive' modifier is not observable. </p></li>
* <li><p> At the discretion of the host system, any module whose name is given
* by a 'requires' directive without the 'transitive' modifier is not
* observable. </p></li>
* <li><p> The algorithm in this step enumerates the same module name twice. This
* indicates a cycle in the 'requires' directives, disregarding any 'transitive'
* modifiers. </p></li>
* </ul>
*
* <p> Otherwise, resolution proceeds to step 2. </p>
*
* <h2> Step 2: Computing the readability graph </h2>
*
* <p> A 'requires' directive (irrespective of 'transitive') expresses that
* one module depends on some other module. The effect of the 'transitive'
* modifier is to cause additional modules to also depend on the other module.
* If module M 'requires transitive N', then not only does M depend on N, but
* any module that depends on M also depends on N. This allows M to be
* refactored so that some or all of its content can be moved to a new module N
* without breaking modules that have a 'requires M' directive. </p>
*
* <p> Module dependencies are represented by the readability graph. The
* readability graph is a directed graph whose vertices are the modules
* enumerated in step 1 and whose edges represent readability between pairs of
* modules. The edges are specified as follows:
*
* <p> First, readability is determined by the 'requires' directives of the
* enumerated modules, disregarding any 'transitive' modifiers:
*
* <ul>
* <li><p> For each enumerated module A that 'requires' B: A "reads" B. </p></li>
* <li><p> For each enumerated module X that is automatic: X "reads" every
* other enumerated module (it is "as if" an automatic module has 'requires'
* directives for every other enumerated module). </p></li>
* </ul>
*
* <p> Second, readability is augmented to account for 'transitive' modifiers:
* <ul>
* <li> <p> For each enumerated module A that "reads" B: </p>
* <ul>
* <li><p> If B 'requires transitive' C, then A "reads" C as well as B. This
* augmentation is recursive: since A "reads" C, if C 'requires transitive'
* D, then A "reads" D as well as C and B. </p></li>
* <li><p> If B is an automatic module, then A "reads" every other enumerated
* automatic module. (It is "as if" an automatic module has 'requires transitive'
* directives for every other enumerated automatic module).</p> </li>
* </ul>
* </li>
* </ul>
*
* <p> Finally, every module "reads" itself. </p>
*
* <p> If any of the following conditions occur in the readability graph, then
* resolution fails:
* <ul>
* <li><p> A module "reads" two or more modules with the same name. This includes
* the case where a module "reads" another with the same name as itself. </p></li>
* <li><p> Two or more modules export a package with the same name to a module
* that "reads" both. This includes the case where a module M containing package
* p "reads" another module that exports p to M. </p></li>
* <li><p> A module M declares that it 'uses p.S' or 'provides p.S with ...' but
* package p is neither in module M nor exported to M by any module that M
* "reads". </p></li>
* </ul>
* <p> Otherwise, resolution succeeds, and the result of resolution is the
* readability graph.
*
* <h2> Root modules </h2>
*
* <p> The set of root modules at compile-time is usually the set of modules
* being compiled. At run-time, the set of root modules is usually the
* application module specified to the 'java' launcher. When compiling code in
* the unnamed module, or at run-time when the main application class is loaded
* from the class path, then the default set of root modules is implementation
* specific (In the JDK implementation it is the module "java.se", if observable,
* and every observable module that exports an API). </p>
*
* <h2> Observable modules </h2>
*
* <p> The set of observable modules at both compile-time and run-time is determined
* by searching an abstract module path. The module path is typically composed
* of search paths that are searched in order: </p>
*
* <ul>
* <li><p> At compile-time only, a compilation module path that contains module
* definitions in source form. </p></li>
* <li><p> The upgrade module path containing compiled definitions of modules
* intended to be used in place of upgradeable modules built-in to the
* environment. </p></li>
* <li><p> The system modules which are the compiled modules built-in to the
* environment. </p></li>
* <li><p> The application module path which contains compiled definitions of
* library and application modules. </p></li>
* </ul>
*
* <h2> 'requires' directives with 'static' modifier </h2>
*
* <p> 'requires' directives that have the 'static' modifier express an optional
* dependence at run time. If a module declares that it 'requires static M' then
* resolution does not search the observable modules for M to satisfy the dependency.
* However, if M is recursively enumerated at step 1 then all modules that are
* enumerated and `requires static M` will read M. </p>
*
* <h2> Completeness </h2>
*
* <p> Resolution may be partial at compile-time in that the complete transitive
* closure may not be required to compile a set of modules. Minimally, the
* readability graph that is constructed and validated at compile-time includes
* the modules being compiled, their direct dependences, and all implicitly
* declared dependences (requires transitive). </p>
*
* <p> At run-time, resolution is an additive process. The recursive enumeration
* at step 1 may be relative to previous resolutions so that a root module,
* or a module named in a 'requires' directive, is not enumerated when it was
* enumerated by a previous (or parent) resolution. The readability graph that
* is the result of resolution may therefore have a vertex for a module enumerated
* in step 1 but with an edge to represent that the module reads a module that
* was enumerated by previous (or parent) resolution. </p>

/**
* Provides services that allow Java programming language agents to instrument
* programs running on the JVM. The mechanism for instrumentation is modification
* of the byte-codes of methods.
*
* <p> An agent is deployed as a JAR file. An attribute in the JAR file manifest
* specifies the agent class which will be loaded to start the agent. Agents can
* be started in several ways:
*
* <ol>
* <li><p> For implementations that support a command-line interface, an agent
* can be started by specifying an option on the command-line. </p></li>
*
* <li><p> An implementation may support a mechanism to start agents some time
* after the VM has started. For example, an implementation may provide a
* mechanism that allows a tool to <i>attach</i> to a running application, and
* initiate the loading of the tool's agent into the running application. </p></li>
*
* <li><p> An agent may be packaged with an application in an executable JAR
* file.</p></li>
* </ol>
*
* <p> Each of these ways to start an agent is described below.
*
*
* <h3>Starting an Agent from the Command-Line Interface</h3>
*
* <p> Where an implementation provides a means to start agents from the
* command-line interface, an agent is started by adding the following option
* to the command-line:
*
* <blockquote>{@code
* -javaagent:<jarpath>[=<options>]
* }</blockquote>
*
* where <i>{@code <jarpath>}</i> is the path to the agent JAR file and
* <i>{@code <options>}</i> is the agent options.
*
* <p> The manifest of the agent JAR file must contain the attribute {@code
* Premain-Class} in its main manifest. The value of this attribute is the
* name of the <i>agent class</i>. The agent class must implement a public
* static {@code premain} method similar in principle to the {@code main}
* application entry point. After the Java Virtual Machine (JVM) has
* initialized, the {@code premain} method will be called, then the real
* application {@code main} method. The {@code premain} method must return
* in order for the startup to proceed.
*
* <p> The {@code premain} method has one of two possible signatures. The
* JVM first attempts to invoke the following method on the agent class:
*
* <blockquote>{@code
* public static void premain(String agentArgs, Instrumentation inst)
* }</blockquote>
*
* <p> If the agent class does not implement this method then the JVM will
* attempt to invoke:
* <blockquote>{@code
* public static void premain(String agentArgs)
* }</blockquote>
* <p> The agent class may also have an {@code agentmain} method for use when
* the agent is started after VM startup (see below). When the agent is started
* using a command-line option, the {@code agentmain} method is not invoked.
*
* <p> Each agent is passed its agent options via the {@code agentArgs} parameter.
* The agent options are passed as a single string, any additional parsing
* should be performed by the agent itself.
*
* <p> If the agent cannot be started (for example, because the agent class
* cannot be loaded, or because the agent class does not have an appropriate
* {@code premain} method), the JVM will abort. If a {@code premain} method
* throws an uncaught exception, the JVM will abort.
*
* <p> An implementation is not required to provide a way to start agents
* from the command-line interface. When it does, then it supports the
* {@code -javaagent} option as specified above. The {@code -javaagent} option
* may be used multiple times on the same command-line, thus starting multiple
* agents. The {@code premain} methods will be called in the order that the
* agents are specified on the command line. More than one agent may use the
* same <i>{@code <jarpath>}</i>.
*
* <p> There are no modeling restrictions on what the agent {@code premain}
* method may do. Anything application {@code main} can do, including creating
* threads, is legal from {@code premain}.
*
*
* <h3>Starting an Agent After VM Startup</h3>
*
* <p> An implementation may provide a mechanism to start agents sometime after
* the the VM has started. The details as to how this is initiated are
* implementation specific but typically the application has already started and
* its {@code main} method has already been invoked. In cases where an
* implementation supports the starting of agents after the VM has started the
* following applies:
*
* <ol>
*
* <li><p> The manifest of the agent JAR must contain the attribute {@code
* Agent-Class} in its main manfiest. The value of this attribute is the name
* of the <i>agent class</i>. </p></li>
*
* <li><p> The agent class must implement a public static {@code agentmain}
* method. </p></li>
*
* </ol>
*
* <p> The {@code agentmain} method has one of two possible signatures. The JVM
* first attempts to invoke the following method on the agent class:
*
* <blockquote>{@code
* public static void agentmain(String agentArgs, Instrumentation inst)
* }</blockquote>
*
* <p> If the agent class does not implement this method then the JVM will
* attempt to invoke:
*
* <blockquote>{@code
* public static void agentmain(String agentArgs)
* }</blockquote>
*
* <p> The agent class may also have a {@code premain} method for use when the
* agent is started using a command-line option. When the agent is started after
* VM startup the {@code premain} method is not invoked.
*
* <p> The agent is passed its agent options via the {@code agentArgs}
* parameter. The agent options are passed as a single string, any additional
* parsing should be performed by the agent itself.
*
* <p> The {@code agentmain} method should do any necessary initialization
* required to start the agent. When startup is complete the method should
* return. If the agent cannot be started (for example, because the agent class
* cannot be loaded, or because the agent class does not have a conformant
* {@code agentmain} method), the JVM will not abort. If the {@code agentmain}
* method throws an uncaught exception it will be ignored (but may be logged
* by the JVM for troubleshooting purposes).
*
*
* <h3>Including an Agent in an Executable JAR file</h3>
*
* <p> The JAR File Specification defines manifest attributes for standalone
* applications that are packaged as <em>executable JAR files</em>. If an
* implementation supports a mechanism to start an application as an executable
* JAR then the main manifest may include the {@code Launcher-Agent-Class}
* attribute to specify the class name of an agent to start before the application
* {@code main} method is invoked. The Java virtual machine attempts to
* invoke the following method on the agent class:
*
* <blockquote>{@code
* public static void agentmain(String agentArgs, Instrumentation inst)
* }</blockquote>
*
* <p> If the agent class does not implement this method then the JVM will
* attempt to invoke:
*
* <blockquote>{@code
* public static void agentmain(String agentArgs)
* }</blockquote>
*
* <p> The value of the {@code agentArgs} parameter is always the empty string.
*
* <p> The {@code agentmain} method should do any necessary initialization
* required to start the agent and return. If the agent cannot be started, for
* example the agent class cannot be loaded, the agent class does not define a
* conformant {@code agentmain} method, or the {@code agentmain} method throws
* an uncaught exception or error, the JVM will abort.
*
*
* <h3> Loading agent classes and the modules/classes available to the agent
* class </h3>
*
* <p> Classes loaded from the agent JAR file are loaded by the
* {@linkplain ClassLoader#getSystemClassLoader() system class loader} and are
* members of the system class loader's {@linkplain ClassLoader#getUnnamedModule()
* unnamed module}. The system class loader typically defines the class containing
* the application {@code main} method too.
*
* <p> The classes visible to the agent class are the classes visible to the system
* class loader and minimally include:
*
* <ul>
*
* <li><p> The classes in packages exported by the modules in the {@linkplain
* ModuleLayer#boot() boot layer}. Whether the boot layer contains all platform
* modules or not will depend on the initial module or how the application was
* started. </p></li>
*
* <li><p> The classes that can be defined by the system class loader (typically
* the class path) to be members of its unnamed module. </p></li>
*
* <li><p> Any classes that the agent arranges to be defined by the bootstrap
* class loader to be members of its unnamed module. </p></li>
*
* </ul>
*
* <p> If agent classes need to link to classes in platform (or other) modules
* that are not in the boot layer then the application may need to be started in
* a way that ensures that these modules are in the boot layer. In the JDK
* implementation for example, the {@code --add-modules} command line option can
* be used to add modules to the set of root modules to resolve at startup. </p>
*
* <p> Supporting classes that the agent arranges to be loaded by the bootstrap
* class loader (by means of {@link Instrumentation#appendToBootstrapClassLoaderSearch
* appendToBootstrapClassLoaderSearch} or the {@code Boot-Class-Path} attribute
* specified below), must link only to classes defined to the bootstrap class loader.
* There is no guarantee that all platform classes can be defined by the boot
* class loader.
*
* <p> If a custom system class loader is configured (by means of the system property
* {@code java.system.class.loader} as specified in the {@link
* ClassLoader#getSystemClassLoader() getSystemClassLoader} method) then it must
* define the {@code appendToClassPathForInstrumentation} method as specified in
* {@link Instrumentation#appendToSystemClassLoaderSearch appendToSystemClassLoaderSearch}.
* In other words, a custom system class loader must support the mechanism to
* add an agent JAR file to the system class loader search.
*
* <h3>Manifest Attributes</h3>
*
* <p> The following manifest attributes are defined for an agent JAR file:
*
* <blockquote><dl>
*
* <dt>{@code Premain-Class}</dt>
* <dd> When an agent is specified at JVM launch time this attribute specifies
* the agent class. That is, the class containing the {@code premain} method.
* When an agent is specified at JVM launch time this attribute is required. If
* the attribute is not present the JVM will abort. Note: this is a class name,
* not a file name or path. </dd>
*
* <dt>{@code Agent-Class}</dt>
* <dd> If an implementation supports a mechanism to start agents sometime after
* the VM has started then this attribute specifies the agent class. That is,
* the class containing the {@code agentmain} method. This attribute is required
* if it is not present the agent will not be started. Note: this is a class name,
* not a file name or path. </dd>
*
* <dt>{@code Launcher-Agent-Class}</dt>
* <dd> If an implementation supports a mechanism to start an application as an
* executable JAR then the main manifest may include this attribute to specify
* the class name of an agent to start before the application {@code main}
* method is invoked. </dd>
*
* <dt>{@code Boot-Class-Path}</dt>
* <dd> A list of paths to be searched by the bootstrap class loader. Paths
* represent directories or libraries (commonly referred to as JAR or zip
* libraries on many platforms). These paths are searched by the bootstrap class
* loader after the platform specific mechanisms of locating a class have failed.
* Paths are searched in the order listed. Paths in the list are separated by one
* or more spaces. A path takes the syntax of the path component of a hierarchical
* URI. The path is absolute if it begins with a slash character ('/'), otherwise
* it is relative. A relative path is resolved against the absolute path of the
* agent JAR file. Malformed and non-existent paths are ignored. When an agent is
* started sometime after the VM has started then paths that do not represent a
* JAR file are ignored. This attribute is optional. </dd>
*
* <dt>{@code Can-Redefine-Classes}</dt>
* <dd> Boolean ({@code true} or {@code false}, case irrelevant). Is the ability
* to redefine classes needed by this agent. Values other than {@code true} are
* considered {@code false}. This attribute is optional, the default is {@code
* false}. </dd>
*
* <dt>{@code Can-Retransform-Classes}</dt>
* <dd> Boolean ({@code true} or {@code false}, case irrelevant). Is the ability
* to retransform classes needed by this agent. Values other than {@code true}
* are considered {@code false}. This attribute is optional, the default is
* {@code false}. </dd>
*
* <dt>{@code Can-Set-Native-Method-Prefix}</dt>
* <dd> Boolean ({@code true} or {@code false}, case irrelevant). Is the ability
* to set native method prefix needed by this agent. Values other than {@code
* true} are considered {@code false}. This attribute is optional, the default
* is {@code false}. </dd>
*
* </dl></blockquote>
*
* <p> An agent JAR file may have both the {@code Premain-Class} and {@code
* Agent-Class} attributes present in the manifest. When the agent is started
* on the command-line using the {@code -javaagent} option then the {@code
* Premain-Class} attribute specifies the name of the agent class and the {@code
* Agent-Class} attribute is ignored. Similarly, if the agent is started sometime
* after the VM has started, then the {@code Agent-Class} attribute specifies
* the name of the agent class (the value of {@code Premain-Class} attribute is
* ignored).
*
*
* <h3>Instrumenting code in modules</h3>
*
* <p> As an aid to agents that deploy supporting classes on the search path of
* the bootstrap class loader, or the search path of the class loader that loads
* the main agent class, the Java virtual machine arranges for the module of
* transformed classes to read the unnamed module of both class loaders.

interface, an agent is started by specifying an option on the command-line.
Implementations may also support a mechanism to start agents some time after the VM has
started. For example, an implementation may provide a mechanism that allows a tool to
<i>attach</i> to a running application, and initiate the loading of the tool's agent into
the running application. The details as to how the load is initiated, is implementation
dependent.
<h3>Command-Line Interface</h3>
<P>
An implementation is not required to provide a way to start agents from the
command-line interface. On implementations that do provide a way to start agents
from the command-line interface, an agent is started by adding this option to
the command-line:
<blockquote>
<code><b>-javaagent:</b></code><i>jarpath[</i><code><b>=</b></code><i>options]</i>
</blockquote>
<i>jarpath</i> is the path to the agent JAR file.
<i>options</i> is the agent options.
This switch may be used multiple times on the same command-line,
thus creating multiple agents.
More than one agent may use the same <i>jarpath</i>.
An agent JAR file must conform to the JAR file specification.
<P>
The manifest of the agent JAR file must contain the attribute <code>Premain-Class</code>. The
value of this attribute is the name of the <i>agent class</i>. The agent class must implement a
public static <code>premain</code> method similar in principle to the <code>main</code> application
entry point. After the Java Virtual Machine (JVM) has initialized, each <code>premain</code> method
will be called in the order the agents were specified, then the real application
<code>main</code> method will be called.
Each <code>premain</code> method must return in order for the startup sequence to proceed.
<P>
The <code>premain</code> method has one of two possible signatures. The JVM first attempts to
invoke the following method on the agent class:
<blockquote>
<code>public static void
premain(String agentArgs, Instrumentation inst);
</code>
</blockquote>
<P>
If the agent class does not implement this method then the JVM will attempt to invoke:
<blockquote>
<code>public static void
premain(String agentArgs);
</code>
</blockquote>
<P>
The agent class may also have an <code>agentmain</code> method for use when the agent is started
after VM startup. When the agent is started using a command-line option, the <code>agentmain</code>
method is not invoked.
<P>
The agent class will be loaded by the system class loader
(see {@link java.lang.ClassLoader#getSystemClassLoader ClassLoader.getSystemClassLoader}). This is
the class loader which typically loads the class containing the application <code>main</code> method.
The system class loader must support a mechanism to add an agent JAR file to the system class path.
If it is a custom system class loader then it must define the
<code>appendToClassPathForInstrumentation</code> method as specified in
{@link Instrumentation#appendToSystemClassLoaderSearch appendToSystemClassLoaderSearch}.
The <code>premain</code> methods will be run under the same security and classloader
rules as the application <code>main</code> method.
There are no modeling restrictions on what the agent <code>premain</code> method may do.
Anything application <code>main</code> can do, including creating threads, is legal from
<code>premain</code>.
<P>
Each agent is passed its agent options via the <code>agentArgs</code> parameter.
The agent options are passed as a single string,
any additional parsing should be performed by the agent itself.
<P>
If the agent cannot be resolved
(for example, because the agent class cannot be loaded,
or because the agent class does not have an appropriate <code>premain</code> method), the JVM will abort.
If a <code>premain</code> method throws an uncaught exception, the JVM will abort.
<h3>Starting Agents After VM Startup</h3>
<p>
An implementation may provide a mechanism to start agents sometime after the
the VM has started. The details as to how this is initiated are implementation
specific but typically the application has already started and its <code>
main</code> method has already been invoked. In cases where an implementation
supports the starting of agents after the VM has started the following applies:
<ol>
<li><p>The manifest of the agent JAR must contain the attribute <code>Agent-Class</code>.
The value of this attribute is the name of the <i>agent class</i>. </p></li>
<li><p>The agent class must implement a public static <code>agentmain</code> method. </p></li>
<li><p>The system class loader (
{@link java.lang.ClassLoader#getSystemClassLoader ClassLoader.getSystemClassLoader}) must
support a mechanism to add an agent JAR file to the system class path.
If it is a custom system class loader then it must define the
<code>appendToClassPathForInstrumentation</code> method as specified in
{@link Instrumentation#appendToSystemClassLoaderSearch appendToSystemClassLoaderSearch}.</li>
</ol>
<P>
The agent JAR is appended to the system class path. This is the class loader that typically loads
the class containing the application <code>main</code> method. The agent class is loaded and the
JVM attempts to invoke the <code>agentmain</code> method. The JVM first attempts to invoke
the following method on the agent class:
<blockquote>
<code>public static void
agentmain(String agentArgs, Instrumentation inst);
</code>
</blockquote>
<P>
If the agent class does not implement this method then the JVM will attempt to invoke:
<blockquote>
<code>public static void
agentmain(String agentArgs);
</code>
</blockquote>
<P>
The agent class may also have an <code>premain</code> method for use when the agent is started
using a command-line option. When the agent is started after VM startup the <code>premain</code>
method is not invoked.
<P>
The agent is passed its agent options via the <code>agentArgs</code> parameter.
The agent options are passed as a single string,
any additional parsing should be performed by the agent itself.
<P>
The <code>agentmain</code> method should do any necessary initialization
required to start the agent. When startup is complete the method should
return. If the agent cannot be started
(for example, because the agent class cannot be loaded,
or because the agent class does not have a conformant <code>agentmain</code> method), the JVM will
not abort. If the <code>agentmain</code> method throws an uncaught exception it will be ignored.
<h3>Deploying Agents in Executable JAR file</h3>
The JAR File Specification defines manifest attributes for standalone applications that are
bundled as <em>executable JAR files</em>. If an implementation supports a mechanism to start
an application as an executable JAR then the main manifest may include the
<code>Launcher-Agent-Class</code> attribute to specify the class name
of an agent to start before the application <code>main</code> method is invoked. The Java
virtual machine attempts to invoke the following method on the agent class:
<blockquote>
<code>public static void
agentmain(String agentArgs, Instrumentation inst);
</code>
</blockquote>
<P>
If the agent class does not implement this method then the JVM will attempt to invoke:
<blockquote>
<code>public static void
agentmain(String agentArgs);
</code>
</blockquote>
<p>
The value of the <code>agentArgs</code> parameter is always the empty string.
<P>
The <code>agentmain</code> method should do any necessary initialization
required to start the agent and return. If the agent cannot be started, for
example the agent class cannot be loaded, the agent class does not define a
conformant <code>agentmain</code> method, or the <code>agentmain</code> method
throws an uncaught exception or error, the JVM will abort.
<h3>Visibility</h3>
The types visible to the agent class are the types visible to the system class
loader. They minimally include the types in packages exported by
<a href="{@docRoot}/java.base-summary.html">java.base</a> and
<a href="{@docRoot}/java.instrument-summary.html">java.instrument</a>.
Whether all {@linkplain ClassLoader#getPlatformClassLoader() platform classes}
are visible or not will depend on the initial module or application.
<p>
Supporting classes that the agent makes visible to the bootstrap class loader
(by means of {@link Instrumentation#appendToBootstrapClassLoaderSearch
appendToBootstrapClassLoaderSearch} or the <code>Boot-Class-Path</code> attribute
specified below) can only link to types defined to the bootstrap class loader.
There is no guarantee that all platform classes are visible to the boot class
loader.
<h3>Manifest Attributes</h3>
The following manifest attributes are defined for an agent JAR file:
<blockquote>
<dl>
<dt><code>Premain-Class</code></dt>
<dd>
When an agent is specified at JVM launch time this attribute
specifies the agent class.
That is, the class containing the <code>premain</code> method.
When an agent is specified at JVM launch time this attribute
is required. If the attribute is not present the JVM will abort.
Note: this is a class name, not a file name or path.
</dd>
<dt><code>Agent-Class</code></dt>
<dd>
If an implementation supports a mechanism to start agents
sometime after the VM has started then this attribute specifies
the agent class.
That is, the class containing the <code>agentmain</code> method.
This attribute is required, if it is not present the agent
will not be started.
Note: this is a class name, not a file name or path.
</dd>
<dt><code>Launcher-Agent-Class</code></dt>
<dd>
If an implementation supports a mechanism to start an application
as an executable JAR then the main manifest may include this
attribute to specify the class name of an agent to start before the
application <code>main</code> method is invoked.
</dd>
<dt><code>Boot-Class-Path</code></dt>
<dd>
A list of paths to be searched by the bootstrap class
loader. Paths represent directories or libraries
(commonly referred to as JAR or zip libraries on
many platforms).
These paths are searched by the
bootstrap class loader after the platform specific
mechanisms of locating a class have failed.
Paths are searched in the order listed.
Paths in the list are separated by one or more spaces.
A path takes the syntax of the path component of a
hierarchical URI. The path is
absolute if it begins with a slash character ('/'),
otherwise it is relative. A relative path is resolved
against the absolute path of the agent JAR file.
Malformed and non-existent paths are ignored.
When an agent is started sometime after the VM has
started then paths that do not represent a JAR file
are ignored.
This attribute is optional.
</dd>
<dt><code>Can-Redefine-Classes</code></dt>
<dd>
Boolean (<code>true</code> or <code>false</code>, case irrelevant).
Is the ability to redefine classes
needed by this agent.
Values other than <code>true</code> are considered <code>false</code>.
This attribute is optional, the default is <code>false</code>.
</dd>
<dt><code>Can-Retransform-Classes</code></dt>
<dd>
Boolean (<code>true</code> or <code>false</code>, case irrelevant).
Is the ability to retransform classes
needed by this agent.
Values other than <code>true</code> are considered <code>false</code>.
This attribute is optional, the default is <code>false</code>.
</dd>
<dt><code>Can-Set-Native-Method-Prefix</code></dt>
<dd>
Boolean (<code>true</code> or <code>false</code>, case irrelevant).
Is the ability to set native method prefix needed by this agent.
Values other than <code>true</code> are considered <code>false</code>.
This attribute is optional, the default is <code>false</code>.
</dd>
</dl>
</blockquote>
<p>
An agent JAR file may have both the <code>Premain-Class</code> and <code>Agent-Class</code>
attributes present in the manifest. When the agent is started on the command-line using
the <code>-javaagent</code> option then the <code>Premain-Class</code> attribute
specifies the name of the agent class and the <code>Agent-Class</code> attribute is
ignored. Similarly, if the agent is started sometime after the VM has started, then
the <code>Agent-Class</code> attribute specifies the name of the agent class
(the value of <code>Premain-Class</code> attribute is ignored).
<h3>Instrumenting code in modules</h3>
As an aid to agents that deploy supporting classes on the search path of the
bootstrap class loader, or the search path of the class loader that loads
the main agent class, the Java virtual machine arranges for the module of
transformed classes to read the unnamed module of both class loaders.
