| * 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. |
