Re: How to override the Netbeans Platform (x) button or the netbeans platform default close operation

I notice you mentioned window listeners. You don't happen to shut down the
JVM outside the LifecycleManager or RCP do you? That could cause some
oddities for sure. What did your closing implementation look like? I
suggest making the simplest example of a platform app using closing and how
you want it to work and see how that works, and if not working, make it
something you can share on GitHub or Bitbucket to get help.

You can also see this:
http://bits.netbeans.org/8.1/javadoc/org-openide-modules/org/openide/modules/OnStop.html

Where the callables ask if it is OK, and the runnables allow you to cleanup
if you allow the shutdown.

If you are questioning the user, you need to be sure you are using some
synchronous question ... Modal Dialog ... Or block some other way ... Like
invokeAndWait ...To return your answer. If you don't do that, then you may
not be returning when you think you are; just being sure.
