Hi Jonathan,
Could you get a thread dump to see what threads remain in the controller
VM? If you started the controller in a shell just press Ctrl+\ to get
the thread dump from the JVM.
I am not sure how the RMI registry terminates when there are still
pending JMX calls, that might be the problem.
Keep us posted with your findings,
Emmanuel
I’m trying to shut down the controller through JMX calls and the
application never exits.
I start the controller with the batch file included with Sequoia. When
we’re shutting down our application, we wish to shut down the
controller. I have a VirtualDatabaseMBean called virtualDB and a
ControllerMBean called controller.
The code goes something like this:
virtualDB.shutdown(Constants.SHUTDOWN_SAFE);
waitForVirtualDBShutdownJMXMessage();
controller.shutdown();
There’s a bit more code in there, but that’s the core.
I get a response from the VirtualDB shutdown that it’s complete and
then it proceeds to shutdown the controller. Everything appears fine,
but I get an exception near the end of the log output. Here’s the
sequence I get:
09:29:50,059 INFO controller.virtualdatabase.VDB Shutting down virtual

It looks like everything is ok except for the RMI problem (I’m
assuming that has to do with shutting down the Jmx Agent), however,
the application doesn’t exit. The controller is still sitting there.
If I try to add in a System.exit(0) command at the end of the
shutdown() method in the controller, I get the following (which hangs
my application):

How do I get the application to exit after shutting down the controller?
