Is there an exception?

no, the log print success

If there are no exceptions, are you checking for something else which shows that the server did not stop? Have you tried debugging the code?

I make a mistake, it can stop, but the next time boot up the web application, there are some exception, it seem I should unregisterMBean and UnicastRemoteObject.unexportObject(registry, false);
is there any example about close JMX?
