FULL PRODUCT VERSION :
java version "1.4.0-beta3"
Java(TM) 2 Runtime Environment, Standard Edition (build
1.4.0-beta3-b84)
Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed
mode)

FULL OPERATING SYSTEM VERSION :
NT 4.0 service pack 5, dual processor
(Don't have the machine now, so I can't run "ver").


A DESCRIPTION OF THE PROBLEM :
Showing a modal dialog box from a JFrame
WindowListener.windowActivated() causes the application
to lock up. This happens before the contents of the
dialog are displayed. This will happen on any window
activation (not just the first). I don't know if it
matters, but I'm on a dual-processor machine.

Not sure if this is swing or awt problem.


REGRESSION. Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile and Run my example program.


EXPECTED VERSUS ACTUAL BEHAVIOR :
The contents of the dialog should be displayed (the
"TEST" button). Under 1.4, this does not happen. No
user input is possible, the application is locked up.


This bug can be reproduced always.

---------- BEGIN SOURCE ----------

   import java.awt.event.*;
   import javax.swing.*;

   public class DialogLockup extends JFrame {
      public static void main(String[] args) {
         DialogLockup frame = new DialogLockup();
         frame.addWindowListener(
               new WindowAdapter() {
                  public void windowActivated(WindowEvente) {
                     JDialog dialog = new JDialog();
                     dialog.setModal(true);
                     dialog.getContentPane().add(new JButton("TEST"));
                     dialog.pack();
                     dialog.setVisible(true);
                  }
               });
      
         frame.setSize(300, 300);
         frame.setVisible(true);
      }
   }

---------- END SOURCE ----------

CUSTOMER WORKAROUND :
Use SwingUtilities.invokeLater() to pop up the dialog.
