    Default nullPointerException with Nimbus l&f

    Hello ! Please help me !

    I've got the following exception when I try to set Nimbus l&f (GTK has the same pb, whereas Motif and Metal work well)

    Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

    I've add to see what helped :
    EventQueue queue = Toolkit.getDefaultToolkit().getSystemEventQueue();
    queue.push(new EventQueue() {
    @Override
    protected void dispatchEvent(AWTEvent event) {
    // System.out.println("info " + event.toString());
    try {
    super.dispatchEvent(event);
    } catch (Throwable t) {
    System.out.println(super.getCurrentEvent());
    System.out.println(event.getSource());
    t.printStackTrace();
    System.out.println(t.getMessage() + " " + t.getClass());
    }
    }
    });
    and I get :
    java.awt.event.InvocationEvent[INVOCATION_DEFAULT,runnable=javax.swing.SystemEven tQueueUtilities$ComponentWorkRequest@64959a7a,noti fier=null,catchExceptions=false,when=1360338783958] on sun.awt.X11.XToolkit@472462b3
    java.lang.NullPointerException
    sun.awt.X11.XToolkit@472462b3
    null

    I've tried also to add the long process into SwingWorker, or call UIManager.setLookAndFeel("com.sun.java.swing.plaf. nimbus.NimbusLookAndFeel") after the initialization of my Frame, but still don't work.
