java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b53)
Java HotSpot(TM) Client VM (build 1.4beta-B53, mixed mode)

This regression was introduced in between Merlin b48 and b50 and still exists in b53.

When the demo application is run, the Exit menu shows a "-X" or "+X" as it's accelerator instead of "Alt-X" as in build 48. The "Alt" prefix is missing.

The bug affects both Solaris and Windows in all look and feels.

--- Accelerator.java ----

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

public class Accelerator extends JFrame {

    public Accelerator() {
JMenuBar menuBar = new JMenuBar();
JMenu menu = new JMenu("File");
menu.setMnemonic('F');
menu.add(new ExitAction());

menuBar.add(menu);
setJMenuBar(menuBar);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
    }


    public static void main(String[] args) {
Accelerator test = new Accelerator();
test.setVisible(true);
    }

    static class ExitAction extends AbstractAction {
public ExitAction() {
super("Exit");
putValue(MNEMONIC_KEY, new Integer('x'));
putValue(ACCELERATOR_KEY,
KeyStroke.getKeyStroke('X', KeyEvent.ALT_MASK));
}
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
    }
}
