 * VM Testbase readme:
 * DESCRIPTION
 *     This JVMTI test is for EM02 scenario of "events and event management" area.
 *     Test executes the following steps for FRAME_POP event:
 *     1)
 *     - adds the <can_generate_frame_pop_events>, <can_suspend> capabilities
 *       during the OnLoad phase;
 *     - sets callbacks for VM_INIT and FRAME_POP event during the OnLoad phase;
 *     - enables all optional events via SetEventNotificationMode during
 *       the OnLoad phase;
 *     - debuggee starts recurisve method with depth=1000 and when defined depth
 *       has been reached, jvmti agent suspend thread and calls NotifyFramePop;
 *     - expects FRAME_POP event is sent 1000 time.
 *     2)
 *     - changes callbacks for choosen event;
 *     - debuggee starts recurisve method with depth=1000 and when defined depth
 *       has been reached, jvmti agent suspend thread and calls NotifyFramePop;
 *     - checks that altered callback works and FRAME_POP event is sent 1000 time.
 *     3)
 *     - sets off callbacks for FRAME_POP event;
 *     - sets callback for VM_DEATH event;
 *     - checks that no FRAME_POP events are sent until VMDeath event.
 * COMMENTS
 *     Modified due to fix of the bug
 *     5010571 TEST_BUG: jvmti tests with VMObjectAlloc callbacks should
 *             be adjusted to new spec
 *     Fixed 5028164 bug.
 *     Fixed
 *     #5045048 TEST_BUG: jvmti tests should synchronize access to static vars
