/**
* The test for the implementation of an object of the type <BR>
* VirtualMachine. <BR>
* <BR>
* The test checks up that results of the method <BR>
* <code>com.sun.jdi.VirtualMachine.canGetOwnedMonitorInfo()</code> <BR>
* complies with its spec. <BR>
* <BR>
* The case for testing includes two threads objects defined <BR>
* in a debuggee and their mirrors in a debugger. <BR>
* The test works as follows. After being started up, <BR> <BR>
* the debuggee creates a 'lockingObject' for synchronizing threads, <BR>
* enters a synchronized block in which it creates new thread, thread2, <BR>
* informs the debugger of the thread2 creation, <BR>
* and is waiting for reply. <BR>
* Since the thread2 use the same locking object in its 'run' method <BR>
* it is locked up until main thread leaves the synchronized block. <BR>
* Upon the receiption a message from the debuggee, the debugger <BR>
* suspends the 'main' thread and gets a boolean value returned by <BR>
* the method VirtualMachine.canGetOwnedMonitorInfo() <BR>
* <BR>
* Then if the value is true the debugger checks up that call to the <BR>
* the method mainThread.ownedMonitors() doesn't throw <BR>
* UnsupportedOperationException. <BR>
* If the value is false the debugger checks up that call to the <BR>
* the method mainThread.ownedMonitors() does throw <BR>
* UnsupportedOperationException. <BR>
