/**
* The test for the implementation of an object of the type <BR>
* ThreadReference. <BR>
* <BR>
* The test checks up that results of the method <BR>
* <code>com.sun.jdi.ThreadReference.popFrames()</code> <BR>
* complies with its spec. <BR>
* <BR>
* The test checks up that <BR>
* a BreakpointRequest in debuggee's third thread <BR>
* is not affected when <BR>
* its second thread is suspended at a breakpoint in a method <BR>
* and method's frame is popped by a debugger. <BR>
* <BR>
* The test has two phases and works as follows. <BR>
* <BR>
* In first phase, <BR>
* upon launching debuggee's VM which will be suspended, <BR>
* a debugger waits for the VMStartEvent within a predefined <BR>
* time interval. If no the VMStartEvent received, the test is FAILED. <BR>
* Upon getting the VMStartEvent, it makes the request for debuggee's <BR>
* ClassPrepareEvent with SUSPEND_EVENT_THREAD, resumes the VM, <BR>
* and waits for the event within the predefined time interval. <BR>
* If no the ClassPrepareEvent received, the test is FAILED. <BR>
* Upon getting the ClassPrepareEvent,
* the debugger sets up the breakpoint with SUSPEND_EVENT_THREAD <BR>
* within debuggee's special methodForCommunication(). <BR>
* <BR>
* In second phase to perform the above check, <BR>
* the debugger and the debuggee perform the following. <BR>
* - The debugger resumes the debuggee and waits for the BreakpointEvent.<BR>
* - The debuggee creates two threads, thread2 and thread3, which will <BR>
* call a tested synchronized poppedMethod() from their run() methods. <BR>
* After getting the threads started, the debuggee invokes the <BR>
* methodForCommunication() to inform the debugger of the threads. <BR>
* - The debugger sets up two breakpoints within the poppedMethod(), <BR>
* one for the thread2 and another one for the thread3, and <BR>
* resumes debuggee's main thread. <BR>
* - The main thread releases the thread2 and the thread3 in the order <BR>
* which makes the thread2 to be suspended at the breakpoint within <BR>
* the poppedMethod and the thread3 to be waiting for releasing the <BR>
* synchronized poppedMethod by the thread2. Then <BR>
* the main thread informs the debugger via methodForCommunication(). <BR>
* - After getting both breakpoint events, from the thread2 and the main,<BR>
* the debugger invokes the popFrames() method and waits for <BR>
* the breakpoint event in poppedMethod from the thread3. <BR>
* If no the event, the test FAILED. <BR>
