SplashScreen class that works in Linux but not Windows?

Question

OK so I wrote this splashscreen class:
public class SplashScreen extends JWindow {
    public SplashScreen(String imageFile, int msecs) {
        Image imgData = getToolkit().getImage(getClass().getResource(imageFile));     
        System.out.println(imageFile);
        // Create label with image on it               
        ImageIcon image = new ImageIcon(imgData);
        // Create label with image as content
        JLabel imageLabel = new JLabel(image);
        // Add label to content pane
        getContentPane().add(imageLabel, BorderLayout.CENTER);
        // Resize window to match image
        pack();
        // Get the size of the screen and the size of the image
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        Dimension imageSize  = imageLabel.getPreferredSize();
        System.out.println(String.format("%d %d", imageSize.width, imageSize.height));
        // Center window on screen
        this.setLocation(screenSize.width/2 - (imageSize.width/2), screenSize.height/2 - (imageSize.height/2));
        // Runnable that handles closing down the screen
        final SplashScreen parent = this;       
        final Runnable closeThread = new Runnable() {
            public void run() {
                parent.setVisible(false);
                parent.dispose();
        // Thread that simple sleeps and then calls the closer
        final int waitTime = msecs;
        Thread waitThread = new Thread(new Runnable() {
            public void run() {
                try {
                    Thread.sleep(waitTime);
                    SwingUtilities.invokeAndWait(closeThread);
                } catch (Exception e) {
                    e.printStackTrace();
        // Display the screen
        setVisible(true);
        // Wait and close
        waitThread.start();              
}Which I call thusly:
gui.SplashScreen sc = new gui.SplashScreen("/images/splashscreen.png", 2000);Obviously this is supposed to display the given image on the screen for 2 seconds before disappearing. My problem is that it works exactly like you'd expect in Linux, but when I run it in windows the image doesn't appear. The app loads and runs fine otherwise. I put some print outs in and verified that it looks like it's finding the image correctly, but then it just doesn't display... I'm stumped, does anyone have any clue why this would be a problem on different platforms?

Seriously? I tried it on two different windows machines and it didn't work.... Maybe it has something to do with how netbeans is jarring stuff up.
