Platform preferences theme detection

[Christopher Schnick]

Well, that is going to be a fun one to debug ... In my application I 
check for a headless environment with 
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices(). If 
you call that one before you initialize your application, the 
preferences detection does no longer update. So if you augment your 
PlatformPreferencesChangedTest application with this main method, it no 
longer works. Also, it throws another exception when clicking on the 
fail button.

|    public static void main(String[] args) {
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices();
         Application.launch(args);
     }|
