On NT4 using JDK114 the MenuShortCuts ctrl+\ and ctrl+/ do not generate action events.

Also some combinations of keys generate action events which they should not. If you
MenuShortCuts keys of ctrl+N,ctrl+C and ctrl+T the following combination of keys will
generate false actions events, blaming the MenuItem with the related shortcut.

ctrl + numericpad fullstop -----> ctrl+N
ctrl + numericpad 3 ------> ctrl+C
ctrl + F5 ------> ctrl+T

Sourcecode to generate the above:

// A Stand alone Test case to show MenuShortCut Items don't work properly

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

public class MenuShortCutTest extends Frame implements ActionListener
{

  private MenuBar menu_bar;
  private Menu main_menu;
  private MenuItem selectall_item,deselectall_item,test_item,cp_item,new_item;

  private TextField text_field;

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

  public MenuShortCutTest()
  {
    // Text Field
    text_field = new TextField();
    add(text_field);

    // Set Up Menu Bar
    menu_bar=new MenuBar();
    this.setMenuBar(menu_bar);
    main_menu = new Menu("Main");

    // Select All
    selectall_item = new MenuItem("SelectAll", new MenuShortcut(KeyEvent.VK
_SLASH));
    main_menu.add(selectall_item);
    selectall_item.addActionListener(this);

    // DeSelect All
    deselectall_item = new MenuItem("DeselectAll", new MenuShortcut(KeyEven
t.VK_BACK_SLASH));
    main_menu.add(deselectall_item);
    deselectall_item.addActionListener(this);

    // Test
    test_item = new MenuItem("Test", new MenuShortcut(KeyEvent.VK_T));
    main_menu.add(test_item);
    test_item.addActionListener(this);

    // Copy and Paste
    cp_item = new MenuItem("Copy+Paste", new MenuShortcut(KeyEvent.VK_C));
    main_menu.add(cp_item);
    cp_item.addActionListener(this);

    // New
    new_item = new MenuItem("New", new MenuShortcut(KeyEvent.VK_N));
    main_menu.add(new_item);
    new_item.addActionListener(this);

    menu_bar.add(main_menu);
    setSize(500,200);
    show();
  }

  public void actionPerformed (ActionEvent e)
  {
    Object o = e.getSource();
    text_field.setText("Action performed by"+o.toString());
  }
}
