/**
* The test for the implementation of an object of the type
* ExceptionRequest.
*
* The test checks that results of the method
* com.sun.jdi.ExceptionRequest.notifyUncaught()
* complies with its spec.
*
* The test checks if a boolean value, an argument of the method
* EventRequestManager.createExceptionRequest(),
* is equal to one returned by the method
* ExceptionRequest.notifyUncaught()
* The cases to check include both true and false.
*
* 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 assertion,
* the debugger and the debuggee perform the following.
* - The debugger
* - sets up two ExceptionRequests with true and false values of
* the notifyUncaught argument,
* - gets the values of the Request with the method
* StepRequest.notifyUncaught(), and
* - compares the values.
*
* In third phase, at the end of the test, the debuggee changes
* the value of the "instruction" which the debugger and debuggee
* use to inform each other of needed actions, and both end.
