* VM Testbase readme:
* 1. Enable events Exception, MethodExit.
* 2. Call a synchronized method which also obtains a monitor.
* 3. Throw an uncaught exception in the method.
* 4. Redefine a class within triggered callbacks Exception, MethodExit
* caused by the uncaught exception. New version contains the changed
* method.
* 5. Pop a currently executed frame within callback MethodExit.
