* @test
*
* @summary converted from VM Testbase nsk/jvmti/AddToBootstrapClassLoaderSearch/bootclssearch002.
* VM Testbase keywords: [quick, jpda, jvmti, onload_only_logic, noras, no_cds]
* VM Testbase readme:
* 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.
