* @summary converted from VM Testbase nsk/jdi/WatchpointEvent/object/object001.
* VM Testbase keywords: [quick, jpda, jdi]
* VM Testbase readme:
* DESCRIPTION
* This test exercises
* com.sun.jdi.event.WatchpointEvent.object() method.
* The test checks the following assertion:
* method WatchpointEvent.object() returns
* correct ObjectReference for instance field and
* null for static field.
* A debugger class - nsk.jdi.WatchpointEvent.object.object001 ;
* a debuggee class - nsk.jdi.WatchpointEvent.object.object001a .
* The test uses supporting nsk/jdi/share classes for launching debuggee
* and for creating communication pipe between debugger and debuggee. The
* debugger and debugee communicates with special commands.
* The debugger creates WatchpointRequests to the fields defined
* in checked class.
* The debugger starts <Eventhandler> thread for listening events delivered
* from debuggee.
* Upon receiving <GO> command from debugger, the debuggee initializes its
* fields and sends command <DONE>.
* The debugger switches to <EventHandler> to listen the event during the
* time specified by <waittime> parameter. Finally debugger shuts down debuggee
* by <QUIT> command.
* If debugger receives WatchpointEvent, it checks the assertion of the test.
* The test also fails if no WatchpointEvent was received.
* COMMENTS
* Test fixed due to bug:
* 4455653 VMDisconnectedException on resume
* Standard method Debugee.endDebugee() is used instead of cleaning
* event queue on debuggee VM exit.
