/**
* The test for the implementation of an object of the type
* EventSet.
*
* The test checks that results of the method
* com.sun.jdi.EventSet.suspendPolicy()
* complies with its spec.
*
* The test checks that for an ExceptionEvent set,
* the method returns a value corresponding to one
* which suspends the most threads.
* The cases to check include event sets containing
* one to three threads with all possible combinations:
* NONE, THREAD, ALL, NONE+THREAD, NONE+ALL,
* THREAD+ALL, NONE+THREAD+ALL
*
* The test has three phases and works as follows.
*
* In first phase,
* upon launching debuggee's VM which will be suspended,
* a debugger waits for the VMStartEvent within a predefined
* time interval. If no the VMStartEvent received, the test is FAILED.
* Upon getting the VMStartEvent, it makes the request for debuggee's
* ClassPrepareEvent with SUSPEND_EVENT_THREAD, resumes the VM,
* and waits for the event within the predefined time interval.
* If no the ClassPrepareEvent received, the test is FAILED.
* Upon getting the ClassPrepareEvent,
* the debugger sets up the breakpoint with SUSPEND_EVENT_THREAD
* within debuggee's special methodForCommunication().
*
* In second phase to check the above,
* the debugger and the debuggee perform the following loop.
* - The debugger sets up a ExceptionRequest,
* resumes the debuggee, and waits for the ExceptionEvent.
* - The debuggee invokes the special method in which
* NullPointerException is thrown to be resulting in the event.
* - Upon getting new event, the debugger
* performs the check corresponding to the event.
*
* Note. To inform each other of needed actions, the debugger and
* and the debuggee use debuggee's variable "instruction".
* In third phase, at the end,
* the debuggee changes the value of the "instruction"
* to inform the debugger of checks finished, and both end.
