Like I said we know the System.exit() is supposed to report a return code out if you called it from a command prompt, so I don't know what code you get if you throw an exception to end the session.  If you don't need that code, normally used for background processes to determine success, throwing the exception could work as well or better.

In many cases it could well be just pot-a-to, pot-ah-to, no different than calling SwingUtilities.invokeLater() versus EventQueue.invokeLater()?  Just the old way and new way of doing essentially the same thing?
