deploying non-jogl files with JNLPAppletLauncher

I have an applet which calls GLCanvas only in some of the cases as a popup window. Actually most of the GUI was built by Netbeans IDE. I’m getting the following error, I’m not sure what the exact reason is.

Here is the snippet where the callAndWait is called in GUI.init


    /** Initializes the applet GUI */
    public void init() {
        try {
            java.awt.EventQueue.invokeAndWait(new Runnable() {
                public void run() {
                    loadImages();
                    initComponents();
                    initDraggableComponents();
                    myGlassPane = new MyGlassPane();
                    setGlassPane(myGlassPane);
                    initListeners();
                }
            });
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

And here is the html file…

The invokeAndWait() call inserts a Runnable into the AWT Event Queue and the calling Thread waits until this Runnable is executed by the AWT Event Thread. This can only work, if you are not already in the AWT Event Thread. I would assume, that the applets init() is always on the Event Thread, so just leave out the Runnable and the invokeAndWait. If you are unsure, you can test if the current Thread is the EventThread with some SwingUtilities method and decide yourself to wrap the init code into a Runnable or not. If you don’t rely on the init code to be finished by the end of the init()-method, you could also use invokeLater() instead of invokeAndWait().
