|
* DESCRIPTION
|
|
* This JVMTI test exercises JVMTI thread function AddToBootstrapClassLoaderSearch().
|
|
* This test checks that AddToBootstrapClassLoaderSearch() adds segment
|
|
* to bootstrap class search path and bootstrap classloader will find
|
|
* debuggee class using that segment.
|
|
* Debuggee class has direct superclass located in the original bootstrap classpath.
|
|
* The following checks are performed by the test:
|
|
* - AddToBootstrapClassLoaderSearch() returns no errors in OnLoad phase
|
|
* - debuggee class will be found by bootstrap classloader using added segment
|
|
* - superclass needed for debuggee class will be also found by bootstrap
|
|
* classloader though located in the original bootstrap classpath
|
|
* - superclass needed for debuggee class will be loaded from bootstrap
|
|
* classpath, not from usual classpath
|
|
* Source of debuggee class 'bootclssearch002' is located in subdirectory 'newclass'.
|
|
* It will be compiled to '$COMMON_CLASSES_LOCATION/newclass', where it usually
|
|
* cannot be found by bootstrap classloader.
|
|
* The superclass 'bootclssearch002p' has two different implementations.
|
|
* Source of "positive" implementation is located in subdirectory 'loadclass'.
|
|
* It will be compiled to '$COMMON_CLASSES_LOCATION/loadclass' that is added
|
|
* to original bootstrap classpath using option -Xbootclasspath/a.
|
|
* This implementation returns PASS.
|
|
* Source of "negative" implementation is located in the currect directory.
|
|
* It will be compiled to '$COMMON_CLASSES_LOCATION/classes' that is available
|
|
* from usual classpath.
|
|
* This implementation prints error and returns FAIL.
|
|
* The agent adds '$COMMON_CLASSES_LOCATION/newclass' directory with debuggee
|
|
* class implementation to the bootstrap class search path in Agent_OnLoad(),
|
|
* and thus the debuggee class should be found by bootstrap classloader.
|
|
* While loading debuggee class the bootstrap classloader should find and load
|
|
* "positive" implementation of superclass available from original bootstrap
|
|
* classpath, but not "negative" implementation available from usual classpath.
|
|
* If AddToBootstrapClassLoaderSearch() returns error in Agent_OnLoad(),
|
|
* then agent returns JNI_ERR and VM fails on initialization.
|
|
* If AddToBootstrapClassLoaderSearch() does not adds segment to bootstrap
|
|
* classloader search path, then debuggee class is not found and VM
|
|
* fails on initialization.
|
|
* If bootstrap classloader cannot find superclass located by the original
|
|
* bootstrap classpath, then VM also fails on initialization.
|
|
* If bootstrap classloader loads "negative" implementation of superclass
|
|
* available from usual classpath, then the debuggee class returns FAIL,
|
|
* and the test fails with exit code 97.
|
|
* Otherwise, if segment is successfully added and debuggee class with positive
|
|
* implementation of superclass are found, loaded, and executed, then it
|
|
* returns PASS. and the test passes with exit code 95.

* COMMENTS
|
|
* Made code cleanup: nsk/share/jvmti/AddToBootstrapClassLoaderSearch/bootclssearch_agent
|
|
* agent is used now.
