/**
* The test for the implementation of an object of the type
* ThreadGroupReference.
*
* The test checks up that results of the method
* com.sun.jdi.ThreadGroupReference.threadGroups()
* complies with its spec.
*
* The case for testing includes four ThreadGroup objects defined
* in a debuggee and their mirrors in a debugger.
* Parenthood relationships between the objects are as follows:
* threadGroups 2&3 are subgroups of threadGroup1
* threadGroup4 is a subgroup of threadGroup3
* The objects are created together with three threads, Thread 2,3,4,
* belonnging to the corresponding subgroups.
* The test works as follows. After being started up,
* the debuggee creates a 'lockingObject' for synchronizing threads,
* enters a synchronized block in which it creates the threads,
* informs the debugger of the threads creation,
* and is waiting for reply.
* Since the threads use the same locking object in their 'run' methods
* they are locked up until main thread leaves the synchronized block.
* Upon the receiption a message from the debuggee,
* the debugger gets mirrors of threadGroups and checks up that:
* - threadGroup4 has 0 threadGroup members;
* - threadGroup3 has 1 threadGroup member;
* - threadGroup1 has 2 threadGroup members with certain names.
