/**
* The test for the implementation of an object of the type
* WatchpointEvent.
*
* The test checks that results of methods in the interface
* <code>com.sun.jdi.WatchpointEvent</code>
* complies with its spec.
*
* The test checks up on the following assertion:
* The number of WatchpointEvents received is equal to
* the number of WatchpointRequestsset up by a debugger.
* Tested are both Access and Modification WatchpointEvents.
*
* The test works as follows.
* - The debugger resumes the debuggee and waits for the BreakpointEvent.
* - The debuggee an object foo of CheckedClass and invokes
* the methodForCommunication to be suspended and
* to inform the debugger with the event.
* - Upon getting the BreakpointEvent, the debugger:
* - set up enabled WatchpointRequests for all fields,
* - resumes the debuggee, and
* - waiting for all expected events to receive.
