/**
* The test for the implementation of an object of the type <BR>
* LocatableEvent. <BR>
* <BR>
* The test checks that results of the method <BR>
* <code>com.sun.jdi.LocatableEvent.thread()</code> <BR>
* complies with its spec. <BR>
* <BR>
* The cases for testing include all Locatable events. <BR>
* The test checks that <BR>
* for each type of LocatableEvent received in a debugger, <BR>
* a value returned by the method invoked on <BR>
* a <type>Event object corresponds to a thread <BR>
* which debuggee's counterpart event was generated in. <BR>
* <BR>
* The test has three 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, <BR>
* the debugger sets up the breakpoint with SUSPEND_EVENT_THREAD <BR>
* within debuggee's special methodForCommunication(). <BR>
* <BR>
* In second phase to check Locatable events, <BR>
* the debugger and the debuggee perform the following. <BR>
* - The debugger resumes the debuggee and waits for the BreakpointEvent.<BR>
* - The debuggee creates a number of threads, one for each check case <BR>
* and invokes the methodForCommunication to be suspended and <BR>
* to inform the debugger with the event. <BR>
* - Upon getting the BreakpointEvent, the debugger <BR>
* gets ThreadReferences mirroring all tested threads in the debuggee,<BR>
* sets up Requests within them to get Events to check up on, <BR>
* resumes the debuggee, waits for events, and upon getting them, <BR>
* compares ThreadReferences put into Requests to ones from Events; <BR>
* if any mismatch, the test FAILED. <BR>
* <BR>
* Note. To inform each other of needed actions, the debugger and <BR>
* and the debuggee use debuggeee's variable "instruction". <BR>
* <BR>
* In third phase when at the end, <BR>
* the debuggee changes the value of the "instruction" <BR>
* to inform the debugger of checks finished, and both end. <BR>
* <BR>
