/**
* The test for the implementation of an object of the type
* WatchpointRequest.
*
* The test checks that results of the method
* com.sun.jdi.WatchpointRequest.field()
* complies with its spec.
*
* The case to test include AccessWatchpointRequest.
* The test checks if a Field object, an argument of the method
* EventRequestManager.createAccessWatchpointRequest(Field),
* is equal to one returned by the method WatchpointRequest.field()
*
* 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 resumes the debuggee and waits for the BreakpointEvent.
* - The debuggee invokes the methodForCommunication to be suspended
* and to inform the debugger with the event.
* - Upon getting the BreakpointEvent, the debugger
* - creates an AccessWatchpointRequest and gets Field object filed1,
* - gets Field object field2 with the method WatchpointRequest.field(),
* - compares the Filed objects.
*
* 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.
