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
database VDB in safe mode : waiting for all current transactions to complete

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?
