 * DESCRIPTION
 *     This JVMTI test exercises JVMTI thread function AddToBootstrapClassLoaderSearch()
 *     in Live phase.
 *     This test checks that AddToBootstrapClassLoaderSearch() adds segment
 *     to bootstrap class search path in Live phase and bootstrap 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:
 *         - AddToBootstrapClassLoaderSearch() returns no errors in Live phase
 *             - in particular it checks that anything other than an
 *               existing JAR file is an invalid path
 *         - debuggee class will be found by bootstrap classloader using added segment
 *     Source of debuggee class 'bootclssearch001' is located in 'bootclssearch001.jar'
 *     which is located in special subdirectory 'newclass/nsk/jvmti/AddToBootstrapClassLoaderSearch/'.
 *     It will be compiled to
 *     '$COMMON_CLASSES_LOCATION/newclass/nsk/jvmti/AddToBootstrapClassLoaderSearch/bootclssearch001.jar'
 *     jar file, where it usually can not be found by bootstrap classloader.
 *     The agent adds this jar to the bootstrap class search path
 *     in VM_INIT callback(), and thus the debuggee class should be found by
 *     bootstrap classloader and executed normally.
 *     If AddToBootstrapClassLoaderSearch() does not adds segment to bootstrap
 *     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.
 * COMMENTS
 *     Ported from bootclssearch001.
