workaround I can see is checking in the window close event if any
displayable windows exist, if not then call System.exit.
When you think you are done:

call this to find out what threads are still  running:

 /**
     * call just before System.exit( 0 ) to find out if there was more
than one thread.
     */
    public static void trackLastThread()
        {
        final int activeCount = Thread.activeCount();
        if ( activeCount <= 1 )
            {
            return;
            }
        final Thread[] ta = new Thread[ activeCount ];
        Thread.enumerate( ta );
        // list just the user threads, not the daemons
        int userCount = 0;
        for ( Thread t : ta )
            {
            if ( !t.isDaemon() )
                {
                userCount++;
