I spent several hours tracking this one down, so I hope this
bug report proves useful. For the testcase provided, a new window
is opened via a JMenu item where the new window obscures the
original window(with the menu still posted). When the new window
is dragged out of the way the posted menu is still drawn on top
of the original window(instead of being removed).

Here's the code to reproduce it:

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

public class jdk13bug extends JFrame {

    public jdk13bug () {
        setTitle("JMenu Repaint Bug");
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });

        JMenuBar mbar = new JMenuBar();
        setJMenuBar(mbar);
        JMenu file = new JMenu("File");
        JMenuItem mi = new JMenuItem("New Window");
        mi.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                new jdk13bug();
            }});
        file.add(mi);
        mbar.add(file);
        pack();
        setSize(400,400);
        setVisible(true);
    }

    public static void main(String[] args) {
        new jdk13bug();
    }
}

1)

When a JMenu creates a JFrame that overlaps the JMenu, the JMenu is not cleared correctly.

In other words, normally after the mouse is released on a menu choice, the menu disappears and the menu command executes. And this still happens in 1.3 -- except when the menu is creating a new window that appears above where the menu used to be. It does not redraw the frame with the menu in it, so after you close the new window, you still see the menu open.

2) Souce code is simple. In the action listener, just do a:
JFrame foo = new JFrame("bar");
...(add elements to Frame)
foo.pack();
foo.show();

And when foo gets closed, you will still see the menu open in the window behind it. Selecting and unselecting the menu again will clear this visual error.

3) No error messages occur

4) No trace information needed

5) Just using the 1.3 plugin

6) NA

This problem is easy to reproduce. Whenever a menu item
generates a new window getting focus, the menu stays down.
  User must click on the menu again to pull it back up.

This is coupled with painting problems.

============ stevef, 3/9/2000 ==============

We see this bug all the time in the deploytool GUI running on NT.
I have tried to reproduce the problem on Solaris without success.
Important: the bug is not seen in all cases where a resulting dialog
obscures the JMenu that originated it. The bug is seen when the width
of the resulting dialog is near or overlaps the border of the dialog.
In the test case I used, if the dialog width was less than this the bug
is not seen. So this may have to do with a race condition related
to repaint of the JFrame border.

I was able to work around this problem by forcing a repaint of the
underlying graphics...this is an ugly fix but without a workaround
the application looks pretty bad. This is because many of the deploytool
GUI dialogs are very large wizards and hence often result in cases where
this bug is reproduced.

My sample code is shown below. You will need to twiddle with the window
size after bringing up the application to reproduce the bug according to
the positions described above. You can ignore the weird GEN comments...
I used the Netbeans tool to write this.

In bug 4264725, it said it is closed and fixed for J2EE. I don't know why the fix

The problem is that during mouse over of several JMenu's in a menu bar, some
menu items in the menu bar do do not refresh properly (there are remnants of
icons from other menu items in the wrong menu item, and sometimes the menu item
icons are partially showing or grayed out.)
The platform is Java 1.3 running on Win98 (rev. 1) on an IBM Thinkpad laptop.
Your response is urgently requested... we are getting close to a product
release, and this would be a MAJOR, HIGHLY VISIBLE defect in our software.
