/**
* The test for the implementation of an object of the type
* EventSet.
*
* The test checks that results of the method
* com.sun.jdi.EventSet.resume()
* complies with its spec.
*
* Test cases include all three possible suspensions, NONE,
* EVENT_THREAD, and ALL, for ThreadDeathEvent sets.
*
* To check up on the method, a debugger,
* upon getting new set for the EventSet,
* suspends VM with the method VirtualMachine.suspend(),
* gets the List of debuggee's threads calling VM.allThreads(),
* invokes the method EventSet.resume(), and
* gets another List of debuggee's threads.
* The debugger then compares values of
* each thread's suspendCount from first and second Lists.
*
* The test works as follows.
* - The debugger sets up a ThreadDeathRequest, resumes
* the debuggee, and waits for the ThreadDeathEvent.
* - The debuggee creates and starts new thread
* to be resulting in the event.
* - Upon getting new event, the debugger
* performs the check corresponding to the event.
* - The debugger informs the debuggee when it completes
* each test case, so it will wait before hitting
* communication breakpoints.
* This prevents the breakpoint SUSPEND_ALL policy
* disrupting the first test case check for
* SUSPEND_NONE, if the debuggee gets ahead of
* the debugger processing.
