/**
|
|
* The test for the implementation of an object of the type
|
|
* EventSet.
|
|
*
|
|
* The test checks that results of the method
|
|
* <code>com.sun.jdi.EventSet.resume()</code>
|
|
* complies with its spec.
|
|
*
|
|
* Test cases include all three possible suspensions, NONE,
|
|
* EVENT_THREAD, and ALL, for ThreadDeathEvent sets.
|
|
*
|
|
* To check up on the method, a debugger,
|
|
* upon getting new set for the EventSet,
|
|
* suspends VM with the method VirtualMachine.suspend(),
|
|
* gets the List of debuggee's threads calling VM.allThreads(),
|
|
* invokes the method EventSet.resume(), and
|
|
* gets another List of debuggee's threads.
|
|
* The debugger then compares values of
|
|
* each thread's suspendCount from first and second Lists.
|
|
*
|
|
* The test works as follows.
|
|
* - The debugger sets up a ThreadDeathRequest, resumes
|
|
* the debuggee, and waits for the ThreadDeathEvent.
|
|
* - The debuggee creates and starts new thread
|
|
* to be resulting in the event.
|
|
* - Upon getting new event, the debugger
|
|
* performs the check corresponding to the event.
|
|
* - The debugger informs the debuggee when it completes
|
|
* each test case, so it will wait before hitting
|
|
* communication breakpoints.
|
|
* This prevents the breakpoint SUSPEND_ALL policy
|
|
* disrupting the first test case check for
|
|
* SUSPEND_NONE, if the debuggee gets ahead of
|
|
* the debugger processing.
