Re: Swing/Fireworks test does not work

Or maybe just listen until the panel has nonzero size and then start the thread:

        mainPanel.addComponentListener(new ComponentAdapter() {
            @Override
            public void componentResized(ComponentEvent e) {
                if ((mainPanel.getWidth() == 0) || (mainPanel.getHeight() == 0))
                    return;
                new Thread() {
                    @Override
                    public void run() {
                        while (true) {
                            addExplosions(5);
                        }
                    }
                }.start();
            }
        });

I finally got around to looking at this. It was caused by the following code sniplet:

        new Thread() {
            @Override
            public void run() {
                while (true) {
                    if ((mainPanel.getWidth() > 0)
                            && (mainPanel.getHeight() > 0)) {
                        addExplosions(5);
                    }
                }
            }
        }.start();

Initally the condition is false, leading this thread to starve other threads. In my case, this gets into an endless loop. Inserting a sleep statement or any other sort of delay per iteration solves the problem for me but obviously this needs to be cleaned up in a more elegant way. I suggest you run FindBugs on the codebase. I suspect it'll find other problems.

The only thing i can think of is to debug the application locally. Specifically, the Fireworks constructor creates a JPanel which paints all the visuals in its overriden paintComponent(). The volleys are created in addExplosions() method and are animated by the matching timeline scenarios.

Since i don't have access to a 64 bit Windows box, i cannot do this myself.

Thanks

    Yes, Windows7 Ultimate 64-bit.

    Yes. Other Swing applications run just fine. Only applications with native code fails if you try mixing 32-bit native DLLs with the 64-bit JVM.
