The settings are still null when you try to use the JOGL renderer. I'll look at existing examples.

Edit.: Rather do that:
@Override
public void start() {
      showSettings = false;
      AppSettings appSettings = new AppSettings(true);
      appSettings.setRenderer("JOGL");
      appSettings.setAudioRenderer("JOAL");
      setSettings(appSettings);
      super.start();
}
