 * DESCRIPTION
 *     This JVMTI test exercises JVMTI thread function AddToSystemClassLoaderSearch()
 *     in Live 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 'systemclssearch002.jar'
 *     which is located in subdirectory 'newclass/nsk/jvmti/AddToSystemClassLoaderSearch/'.
 *     It will be compiled to
 *     '$COMMON_CLASSES_LOCATION/newclass/nsk/jvmti/AddToSystemClassLoaderSearch/systemclssearch002.jar'
 *     jar file where it usually cannot be found by system classloader.
 *     If AddToSystemClassLoaderSearch() does not adds segment to system
 *     classloader search path, then debuggee class is not found and VM
 *     fails on initialization.
 *     If system classloader cannot find superclass located by the original
 *     system classpath, then VM also 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.
