|
* DESCRIPTION
|
|
* This JVMTI test exercises JVMTI thread function AddToBootstrapClassLoaderSearch().
|
|
* This test checks that AddToBootstrapClassLoaderSearch() adds segment
|
|
* to bootstrap class search path in OnLoad phase, but debuggee class
|
|
* located by this segment will no be loaded if this class is available
|
|
* from the original bootstrap classpath.
|
|
* The following checks are performed by the test:
|
|
* - AddToBootstrapClassLoaderSearch() returns no errors in OnLoad phase
|
|
* - debuggee class located by the original bootstrap classpath will be loaded
|
|
* - debuggee class located by the added segment will NOT be loaded
|
|
* There are two different impelmentations of debuggee class 'bootclssearch003'.
|
|
* Source of "positive" implementation is located in subdirectory 'loadclass'.
|
|
* It will be compiled to '$COMMON_CLASSES_LOCATION/loadclass' and added to
|
|
* original bootstrap classpath using option +Xbootclasspath/a.
|
|
* This implementation returns PASS status.
|
|
* Source of "negative" implementation is located in subdirectory 'newclass'.
|
|
* It will be compiled to '$COMMON_CLASSES_LOCATION/newclass' and added
|
|
* to bootstrap class search path with AddToBootstrapClassLoaderSearch().
|
|
* This implementation returns prints error and returns FAIL status.
|
|
* The agent adds subdirectory '$COMMON_CLASSES_LOCATION/newclass' to
|
|
* the bootstrap classloader search path in Agent_OnLoad(), and expects
|
|
* that positive implementation of debuggee class will be loaded and
|
|
* executed.
|
|
* If AddToBootstrapClassLoaderSearch() returns error in Agent_OnLoad(),
|
|
* then agent returns JNI_ERR and VM fails on initialization.
|
|
* If negative version of debuggee class will be loaded and executed,
|
|
* then it returns FAIL and test fails with exit code 97.
|
|
* Otherwise, if positive version of debuggee class will be loaded and executed,
|
|
* then it returns PASS and test passes with exit code 95.
|
|
* COMMENTS
|
|
* Made code cleanup: nsk/share/jvmti/AddToBootstrapClassLoaderSearch/bootclssearch_agent
|
|
* agent is used now.
