 * DESCRIPTION
 *     This JVMTI test is for EM02 scenario of "events and event management" area.
 *     Test executes the following several steps for events COMPILED_METHOD_LOAD,
 *     COMPILED_METHOD_UNLOAD:
 *       1)
 *         - adds the <can_generate_compiled_method_load_events> capability in
 *           the OnLoad phase
 *         - sets callbacks for VM_INIT and chosen events during the OnLoad phase
 *         - enables events via SetEventNotificationMode during the OnLoad phase
 *           for all optional events.
 *         - provides the state to provoke generation of chosen events
 *         - checks that VM_INIT and chosen events were sent
 *       2)
 *         - changes callbacks for chosen events
 *         - provides the state to provoke generation of chosen events
 *         - checks that chosen events were sent
 *         - checks that altered callback works.
 *       3)
 *         - sets off callbacks for chosen events
 *         - sets callback for VM_DEATH event
 *         - checks that no chosen events are sent until VMDeath event.
