 * @summary converted from VM Testbase nsk/jvmti/AddToBootstrapClassLoaderSearch/bootclssearch003.

 * VM Testbase readme:
 * 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.
