| /** |
| * 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.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> |
| * catchs InterruptedException; <BR> |
| * Then the debugger <BR> |
| * asks the debuggee to check up on its thread2 state <BR> |
| * which should be "not alive" if the thread2 was resumed. <BR> |
