The following code triggers a NullPointerException:

import java.awt.Frame;
import java.awt.event.WindowAdapter;

public class Bug_DSB_19971216 {
public static void main(String [] argv)
{
           Frame f = new Frame();
           f.addWindowListener(new WindowAdapter() { });
           f.dispose();
}
}


If Windows didn't suck, I'd cut and paste the
the stack trace. However, it does, so here is a
paraphrase, transcribed by hand:

NullPointerException
   at Toolkit.getEventQueue(line 670)
   at Window.postWindowEvent(line 165)
   at Window.dispose(line 182)
   at Frame.dispose(line 37)
   at <my class>

Apparently, dispose() was never tested without
calling show(). (Calling show() causes the null
pointer exception to disappear.)
