 * DESCRIPTION
 *     This JVMTI test exercises JVMTI thread function AddToSystemClassLoaderSearch()
 *     in OnLoad phase.
 *     This test checks that AddToSystemClassLoaderSearch() adds segment
 *     to system class search path and system classloader will find
 *     debuggee class using that segment while loading debugge supper class
 *     from original classpath.
 *     The following checks are performed by the test:
 *         - AddToSystemClassLoaderSearch() returns no errors in OnLoad phase
 *         - debuggee class will be loaded from system
 *           classpath using added segment
 *         - superclass needed for debuggee class will be found by system
 *           classloader using original classpath
 *     Source of debuggee class 'systemclssearch002' 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.
 *     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
 *     classloader search path, then debuggee class is not found and VM
 *     fails on initialization.
 *     If segment is successfully added and debuggee super class are found, loaded, and executed,
 *     then it returns PASS. and the test passes with exit code 95.
