SYNOPSIS
--------
AWT: Unexpected MenuBar width and frame overlap

OPERATING SYSTEM
----------------
Windows only

FULL JDK VERSION
----------------
All (JDK 7, 6, 5.0 and 1.4.2)
Including JDK 7 b142

PROBLEM DESCRIPTION
-------------------
If the frame size is smaller than a MenuBar's width, the MenuBar overlaps the edge of the frame and seems to be highlighted incorrectly when it has the focus.

STEPS TO REPRODUCE
------------------
1. Compile and run the test program MenuBarTest1
2. Press F10, or click on the MenuBar, to move focus to the MenuBar.
3. Observe two related issues:
     b) The far right of the MenuBar overlaps the edge of the frame
     a) MenuBar is highlighted, but the overlapping section on the far
        right remains un-highlighted.

The Swing test (MenuBarTestSwing) can be used to observe the correct behaviour.

TESTCASE
--------

AWT test (behaves incorrectly)

import java.awt.*;
import java.awt.event.*;

class MenuBarTest1 extends Frame {
    MenuBarTest1 () {
        setTitle("MenuBarTest1");
        MenuBar menubar= new MenuBar();
        Menu menu = menubar.add(new Menu("mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm"));
        setMenuBar(menubar);
        setSize(100, 50);
        addWindowListener(new WindowAdapter() {
                              public void windowClosing(WindowEvent e) { System.exit(0);}
                          });
        setLocationRelativeTo(null);
        setVisible(true);
    }
    public static void main(String[] args) {
        new MenuBarTest1();
    }
}

Equivalent test with Swing (behaves correctly):

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

class MenuBarTestSwing extends JFrame {
    MenuBarTestSwing () {
        setTitle("MenuBarTest1");
        JMenuBar menubar= new JMenuBar();
        JMenu menu = menubar.add(new JMenu("mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm"));
        setJMenuBar(menubar);
        setSize(100, 50);
        addWindowListener(new WindowAdapter() {
                              public void windowClosing(WindowEvent e) { System.exit(0);}
                          });
        setLocationRelativeTo(null);
        setVisible(true);
    }
    public static void main(String[] args) {
        new MenuBarTestSwing();
    }
}
