| /** |
| * 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> |
