/**
* The test for the implementation of an object of the type <BR>
* Method. <BR>
* <BR>
* The test checks up that results of the method <BR>
* <code>com.sun.jdi.Method.isObsolete()</code> <BR>
* complies with its spec. <BR>
* <BR>
* The test checks up on the following assertion: <BR>
* true if this method has been replaced by a non-equivalent <BR>
* method using VirtualMachine.redefineClasses(java.util.Map).<BR>
* The test checks that isObsolete() returns false if <BR>
* the tested method was redefined with itself <BR>
* which is certainly equivalent. <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 the assetion, <BR>
* the debugger and the debuggee perform the following . <BR>
* - The debugger resumes the debuggee and waits for the BreakpointEvent.<BR>
* - The debuggee loads the class to be redefined and invokes <BR>
* the methodForCommunication to be suspended and <BR>
* to inform the debugger with the event. <BR>
* - Upon getting the BreakpointEvent, the debugger
* - gets a Method object mirroring a method in the class, <BR>
* - checks that isObsolete() invoked on the object, returns false; <BR>
* - redefines the class; <BR>
* - checks again that isObsolete() invoked on the object, <BR>
* returns false. <BR>
* <BR>
* In third phase the debuggee changes the value of the "instruction" <BR>
* to inform the debugger of checks finished, and both end. <BR>
* <BR>
