Java6 splash screen in java webstart

Question

I can't get the java 6 splash screen working when running as a webstart application .
I don't mean the splash you get while downloading but the one that's been introduced in java 6 that's showing while your app is starting.
So far I tried adding it in the manifest file of the main jar, adding the classpath switch in the jnlp file , adding the classpath switch in the JAVAWS_VM_ARGS but none worked.
Is there any documentation on this ? Or how should it work ?

Here's a very simple version:
public class SplashScreen extends JWindow {
    public SplashScreen () {
      JLabel image = new JLabel(new ImageIcon(SplashScreen.class.getResource("icons/splash.gif")));
      this.getContentPane().add(image, null);
      this.pack();
      Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
      Dimension imageSize = image.getPreferredSize();
      this.setLocation(screenSize.width/2 - (imageSize.width/2),     screenSize.height/2 - (imageSize.height/2));
      this.setVisible(true);
}This assumes a sub-folder in the same folder as your SplashScreen class named icons, containing a file splash.gif.
You will need to dispose() of the SplashScreen object when you have finished with it.
