Thread: nullPointerException with Nimbus l&f

Hello !
I've been searching everywhere for the following exception, but still don't find the answer. Please help !
I'm using Nimbus Look and Feel, and I get follow exception (GTKLookAndFeel has the same problem, whereas Metal, MotifLookAndFeel work well) :

I've tried :
- add SwingWorker thread for the long process
- call UIManger.setLookAndFeel("com.sun.java.swing.plaf.n imbus.NimbusLookAndFeel") after initialize my Frame
- add :
EventQueue queue = Toolkit.getDefaultToolkit().getSystemEventQueue();
queue.push(new EventQueue() {
@Override
protected void dispatchEvent(AWTEvent event) {
try {
super.dispatchEvent(event);
} catch (Throwable t) {
System.out.println(super.getCurrentEvent());
System.out.println(event.getSource());
t.printStackTrace();
System.out.println(t.getMessage() );
}
}
});
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

Someone can help me ?

Are you sure that you're scrupulously careful to start *all* Swing code on the event dispatch thread, including the code that creates and displays the application? Try creating a minimal example that reproduces this problem so that we can test and modify it, an SSCCE.

Hello ! I've tried to put some lines, but apparently, I can't post it. Never mind, I've find an object is not created correctly in a librery.
Thank you curmudgeon !
