* @test
*
* @summary converted from VM Testbase nsk/jdi/VMStartEvent/thread/thread001.
* VM Testbase keywords: [quick, jpda, jdi]
* VM Testbase readme:
* DESCRIPTION
* The test exercises
* com.sun.jdi.event.VMStartEvent.thread() method.
* The test checks the following assertions:
* - VMStartEvent is received without creating any EventRequest,
* - VMStarEvent.thread() returns valid ThreadReference
* to the thread in target VM,
* A debugger class - nsk.jdi.VMStartEvent.thread.thread001 ;
* a debuggee class - nsk.jdi.VMStartEvent.thread.thread001a .
* 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 starts special thread <EventHandler> for listening events
* delivered from debuggee.
* The debugger resumes debuggee and waits for command <READY>.
* Upon starting debuggee sends command <READY> and waits for command <QUIT>
* from debugger and completes upon receiving.
* The debugger switches <EventHandler> to listen the event during
* the time specified by <waittime> parameter.
* If the debugger receives VMStartEvent, it checks all assertions
* of the test.
* The test fails if any of the checks failed.
* COMMENTS
* Test fixed due to bug:
* 4455653 VMDisconnectedException on resume
* Test updated to prevent possible VMDisconnectedException on VMDeathEvent:
* - standard method Debugee.endDebugee() is used instead of cleaning event queue
