/**
* The test for the implementation of an object of the type
* EventSet.
*
* The test checks that results of the method
* <code>com.sun.jdi.EventSet.resume()</code>
* complies with its spec.
*
* Test cases include all three possible suspensions, NONE,
* EVENT_THREAD, and ALL, for ClassPrepareEvent sets.
*
* To check up on the method, a debugger,
* upon getting new set for ClassPrepareEvent,
* suspends VM with the method VirtualMachine.suspend(),
* gets the List of geduggee's threads calling VM.allThreads(),
* invokes the method EventSet.resume(), and
* gets another List of geduggee's threads.
* The debugger then compares values of
* each thread's suspendCount from first and second Lists.
*
* The test works as follows.
* - The debugger resumes the debuggee and
* waits for the ClassPrepareEvents.
* - The debuggee creates three threads, running one by one and
* making special clases loaded and prepared to create the Events
* - Upon getting the Events,
* the debugger performs the check required.
