 * DESCRIPTION
 *     This JVMTI test exercises JVMTI thread function AddToSystemClassLoaderSearch()
 *     in OnLoad phase.
 *     This test checks that AddToSystemClassLoaderSearch() adds segment
 *     to system class search path in OnLoad phase and system classloader
 *     will find debuggee class using that segment.
 *     Debuggee class does not have direct superclass to be loaded too.
 *     The following checks are performed by the test:
 *         - AddToSystemClassLoaderSearch() returns no errors in OnLoad phase
 *         - debuggee class will be found by system classloader using added segment
 *     Source of debuggee class 'systemclssearch001' is located in special subdirectory
 *     'newclass' and thus will be compiled to '$COMMON_CLASSES_LOCATION/newclass'
 *     subdirectory, where it usually can not be found by system classloader.
 *     The agent adds this subdirectory to the system class search path
 *     in Agent_OnLoad(), and thus the debuggee class should be found by
 *     system classloader and executed normally.
 *     If AddToSystemClassLoaderSearch() returns error in Agent_OnLoad(),
 *     then agent returns JNI_ERR and VM fails on initialization.
 *     If AddToSystemClassLoaderSearch() does not adds segment to system
 *     class search path, then debuggee class is not found and VM fails on
 *     initialization.
 *     Otherwise, if debuggee class is found, loaded, executed, it returns PASS
 *     and the test passes with exit code 95.
