FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-ea-b33)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b33, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
Event.WINDOW_DESTROY is no longer sent to handleEvent method.

In MS windows all frames have a top control bar with minimize, maximize and close. The "close" control will generate an event in AWT, however for some reason the event is no longer being generated or being routed to the proper frame/window thus it is impossible to close frames/windows of legacy applications (in Java) under the EA release.

This may be similar to a solaris 10, x86 bug in which the focus is wrong for a window close event.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
import java.awt.*;
import java.awt.event.*;
import com.quantumsi.util.awt.ExitingFrame;

public class TT extends Frame {

    public TT() {
        this.setSize(400,400);
        // WORK-AROUND NEWER EVENT LOOP VIA INNER CLASS
        /*
        this.addWindowListener(new WindowAdapter() {
           public void windowClosing(WindowEvent e) {
               System.exit(0);
           }
         });
         */
        this.show();
    }
    // WORKS IN ALL JVM BUT EA J2SE 6.0
    public boolean handleEvent(Event evt) {
        if (evt.id == Event.WINDOW_DESTROY) {
            System.exit(0);
        }
        return super.handleEvent(evt);
    }

    public static void main(String[] args) {
        TT frame = new TT();
    }
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The Frame/Window [ and application ] should exit
ACTUAL -
nothing happens the window stays active and the program does not exit

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.awt.*;
import java.awt.event.*;
import com.quantumsi.util.awt.ExitingFrame;

public class TT extends Frame {

    public TT() {
        this.setSize(400,400);
        // WORK-AROUND NEWER EVENT LOOP VIA INNER CLASS
        /*
        this.addWindowListener(new WindowAdapter() {
           public void windowClosing(WindowEvent e) {
               System.exit(0);
           }
         });
         */
        this.show();
    }
    // WORKS IN ALL JVM BUT EA J2SE 6.0
    public boolean handleEvent(Event evt) {
        if (evt.id == Event.WINDOW_DESTROY) {
            System.exit(0);
        }
        return super.handleEvent(evt);
    }

    public static void main(String[] args) {
        TT frame = new TT();
    }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Use:

        this.addWindowListener(new WindowAdapter() {
           public void windowClosing(WindowEvent e) {
               System.exit(0);
           }
         });

However, all existing legacy AWT applications using handleEvent
no longer work WRT the "close" framee bar decorator control. So an
alternative approach might be to generate the missing event:

        this.addWindowListener(new WindowAdapter() {
           public void windowClosing(WindowEvent e) {
               handleEvent(new Event(this,Event.WINDOW_DESTROY,null));
           }
         });

Release Regression From : 1.5.0
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
