| * 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.ThreadReference.isSuspended()</code> <BR> |
| * complies with its spec. <BR> |
| * The test checks up the following case: <BR> |
| * - a debuggee with second thread, thread2 started up and <BR> |
| * locked up at a synchronized block, <BR> |
| * - suspending the thread2 with ThreadReference.suspend() <BR> |
| * after making debugger's EventQueue empty. |
| * <BR> |
| * After being started up, the debuggee : <BR> |
| * - creates a 'lockingObject'for synchronizing threads; <BR> |
| * - enters into the synchronized block <BR> |
| * in which it creates the thread2; <BR> |
| * - informs a debugger of the thread2 creation, <BR> |
| * and is waiting for an instruction. <BR> |
| * Since thread2 uses the same lockingObject in its 'run' method <BR> |
| * it is locked up until the debuggee leaves the synchronized block. <BR> |
| * Upon the receiption a message from the debuggee, the debugger <BR> |
| * - removes all events from an EventQueue object; <BR> |
| * - suspends thread2 with ThreadReference.suspend(); <BR> |
| * - checks up that the thread2 is suspended. <BR> |
