/**
|
|
* The test for the implementation of an object of the type <BR>

* <BR>
|
|
* The test checks up that results of the method <BR>
|
|
* <code>com.sun.jdi.VirtualMachine.dispose()</code> <BR>
|
|
* complies with its specification. <BR>
|
|
* The test checks up that after call to VirtualMachine.dispose(),<BR>
|
|
* a method invocations executing in the target VM is continued,<BR>
|
|
* and upon completion of the method invocation, <BR>
|
|
* the invoking thread continues from the location where <BR>
|
|
* it was originally stopped. <BR>
|
|
* <BR>
|
|
* The test work as follows. <BR>
|
|
* Upon its launch the debuggee : <BR>
|
|
* creates new thread, thread2 which is waiting until <BR>
|
|
* the main thread leaves a synchronized block, and <BR>
|
|
* informs the debugger of the thread creation. <BR>
|
|
* The thread2 contains a method to be invoked from the debugger<BR>
|
|
* The debugger : <BR>
|
|
* sets up a breakpoint for debuggee's thread2, <BR>
|
|
* instructs the debuggee to leave the synchronized block in <BR>
|
|
* order to get its thread2 suspended at the breakpoint, <BR>
|
|
* waits for a reply from the debuggee. <BR>
|
|
* The debuggee : <BR>
|
|
* leaves the synchronized block and <BR>
|
|
* enter another synchronized block to lock itself at a monitor<BR>
|
|
* which the method "runt2" to be invoked from <BR>
|
|
* the debugger will unlock, <BR>
|
|
* informs the debugger and waits for new instruction. <BR>
|
|
* The debugger : <BR>
|
|
* upon getting the thread2 at the breakpoint, <BR>
|
|
* creates its own Thread object, named thread2 too, <BR>
|
|
* gets its thread2 running; <BR
|
|
* the thread2 invokes the method "runt2" within <BR>
|
|
* debuggee's thread2 suspended at the breakpoint; <BR>
|
|
* the method is at once locked at the monitor holding by <BR>
|
|
* debuggee's main thread; <BR>
|
|
* instructs the debuggee to check whether "runt2" is invoked.<BR>
|
|
* The debuggee : <BR>
|
|
* upon getting unlocked by "runt2", <BR>
|
|
* informs the debugger and waits for new instruction. <BR>
|
|
* The debugger :
|
|
* clears interruption status, <BR>
|
|
* invokes vm.dispose() that results in <BR>
|
|
* VMDisconnectException in the thread2 <BR>
|
|
* which has been suspended after invoking "runt2" <BR>
|
|
* but after exception it is resumed and sends interruption<BR>
|
|
* to the main thread; <BR>
|
|
* if the interruption is not received yet, <BR>
|
|
* sleeps for a predefined waitTime and within this time <BR>
