/**
* The test for the implementation of an object of the type
* VirtualMachine.
*
* The test checks up that results of the method
* com.sun.jdi.VirtualMachine.dispose()
* complies with its specification.
* The test checks up that after call to VirtualMachine.dispose(),
* debuggee's thread suspended before the call by a debugger,
* with method ThreadReference.suspend(), is resumed and runs.
*
* The test work as follows.
* Upon launch the debuggee creates new thread which is waiting
* until a main thread leaves a synchronized block, and informs
* the debugger of the thread creation. The debugger suspends
* the tested thread, performs vm.dispose() and sleeps
* for a predefined time-test parameter. Then the debugger
* asks the debuggee to check up on the tested thread state
* which should be "not alive" if the thread was resumed.
