 * DESCRIPTION
 *     The test implements EX03 scenario of test plan for
 *     Extension Mechanism.
 *     The test agent performs the following actions
 *     and checks:
 *        - search for IsClassUnloadingEnabled function in the list
 *          returned by GetExtentionFunctions' and verifies that
 *          it returns JNI_TRUE. Otherwise the test fails and exits;
 *        - search for ClassUnload in the list returned by
 *          GetExtensionEvents and sets callback if the event is
 *          found;
 *        - waits until the debugged 'ex03t001' class loads axiliary
 *         'ext03t001a' class and unloads it;
 *        - checks that ClassUnload was received;
 *        - unsets callback for the event;
 *        - waits until the debugged 'ex03t001' class loads axiliary
 *         'ext03t001b' class and unloads it;
 *        - checks that ClassUnload was not received;
