How can the RMI registry be stopped programatically?

Question

I would like to stop the RMI registry programmatically. I thought this would be as trivial as calling some stop() or shutdown() method on classes LocateRegistry or Naming but there is no such method.

Things I have tried

• I have tried to unregister all services and wait for the Registry's thread to end by itself gracefully, as proposed in some sites, but it does not seem to work (see #2 below).
• I have tried the recipe provided in this similar question but although it stops the Registry the program as a whole does not stop (see #3 below).
• I have taken into account the answer provided in this other question and made sure that I unexport the actual result of creating the registry and not a stub (see #3 below).

Code examples

1. If I have a trivial program that only creates the registry and does nothing else, it ends successfully.

   // This is the only code in main() Registry registry = LocateRegistry.createRegistry(1099); // reaches the end of main() and stops

2. As soon as a service is registered, the Java Virtual Machine will not stop --- presumably because the Registry's has a thread running in the background. This would make sense if there were services registered but not so much if there are none (at least given the behaviour described above in #1):

   // This is the only code in main() Registry registry = LocateRegistry.createRegistry(1099); Naming.rebind("///name", new SomeRemoteServer()); Naming.unbind("name"); // never stops - must be killed with Ctrl-C

3. At this point, it does not make any different if I try to unexport the Registry. The Registry is stopped (no more services can be registered to / unregistered from it) but the program continues running.

   // This is the only code in main() Registry registry = LocateRegistry.createRegistry(1099); Naming.rebind("///name", new EchoServer()); Naming.unbind("name"); if (registry != null) { UnicastRemoteObject.unexportObject(registry, true); } // // If executed, next line throws NoSuchObjectException // Naming.rebind("///name", new EchoServer()); // // main program never stops - must be killed with Ctrl-C

In short, the question is whether it is possible to stop the RMI Registry programmatically once (a) it has been created and (b) a service has been registered on it? Thanks in advance.
