ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
When using the screen menu bar functionality on Mac OS X, if the title of your help menu is Help, Java or Mac OS (can't tell which) adds additional features to the menu to make it behave like a proper Mac OS X help menu. For instance, it enables the search box to search for menu actions.

However, if the title of your help menu is anything else (which it is likely to be if you're not using an English application), it lacks these additional items, no longer looking anything like a proper help menu.

Aside from not working with JMenuBar, what's even more surprising is that it doesn't work with MenuBar either, even though it has a method specifically for indicating which menu is the help menu.



REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.SwingUtilities;
import javax.swing.WindowConstants;

public class HelpMenuTest implements Runnable {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new HelpMenuTest());
    }

    @Override
    public void run() {
        System.setProperty("apple.laf.useScreenMenuBar", "true");

        JFrame frame = new JFrame();

        // Works:
// JMenuBar menuBar = new JMenuBar();
// JMenu helpMenu = new JMenu("Help");
// menuBar.add(helpMenu);
// frame.setJMenuBar(menuBar);

        // Doesn't work:
        JMenuBar menuBar = new JMenuBar();
        JMenu helpMenu = new JMenu("Hilfe");
        menuBar.add(helpMenu);
        frame.setJMenuBar(menuBar);

        // Doesn't work either (odd, because I specifically told it which one was the help menu.)
// MenuBar menuBar = new MenuBar();
// Menu helpMenu = new Menu("Hilfe");
// menuBar.add(helpMenu);
// menuBar.setHelpMenu(helpMenu);
// frame.setMenuBar(menuBar);

        frame.setSize(200, 200);
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}
