 * DESCRIPTION
 *     This JVMTI test exercises JVMTI thread function AddToBootstrapClassLoaderSearch()
 *     in Live phase (actually only in VM_INIT callback).
 *     This test checks that AddToBootstrapClassLoaderSearch() can add two segments
 *     to bootstrap class search path in Live phase, and debuggee class will be
 *     loaded from the first segment even if it is found in the second segment too,
 *     The following checks are performed by the test:
 *         - AddToBootstrapClassLoaderSearch() adds two segments and returns
 *           no errors in Live phase
 *             - also it checks that anything other than an
 *               existing JAR file is an invalid path
 *         - debuggee class located by the first added segment will be loaded
 *         - debuggee class located by the second added segment will NOT be loaded
 *     There are two different implementations of debuggee class 'bootclssearch004'.
 *     Source of "positive" implementation is located in jar file 'bootclssearch004.jar'
 *     which is located in subdirectory 'newclass01/nsk/jvmti/AddToBootstrapClassLoaderSearch/'.
 *     It will be compiled to
 *     '$COMMON_CLASSES_LOCATION/newclass01/nsk/jvmti/AddToBootstrapClassLoaderSearch/bootclssearch004.jar',
 *     that will be added first to bootstrap class search path.
 *     This implementation returns PASS.
 *     Source of "negative" implementation is located in jar file 'bootclssearch004.jar'
 *     which is located in subdirectory 'newclass02/nsk/jvmti/AddToBootstrapClassLoaderSearch/'.
 *     It will be compiled to
 *     '$COMMON_CLASSES_LOCATION/newclass02/nsk/jvmti/AddToBootstrapClassLoaderSearch/bootclssearch004.jar',
 *     that will be added second to bootstrap class search path.
 *     This implementation returns FAIL.
 *     The agent adds both jars to the bootstrap class search path
 *     in VM_INIT callback, and expects that positive implementation of debuggee class
 *     from the first added segment will be loaded and executed.
 *     If AddToBootstrapClassLoaderSearch() returns error in VM_INIT callback,
 *     then VM fails on initialization.
 *     If negative implementation of debuggee class is loaded and executed,
 *     then it returns FAIL and test fails with exit code 97.
 *     Otherwise, if both segments are successfully added and positive implementation
 *     of debuggee class is loaded and executed, then it returns PASS and test
 *     passes with exit code 95.
