On Mac OS X, quiting with unsaved changes asks for saving twice

[Zverikk]

1. On Mac OS X, run JOSM.
2. Download an area, modify something.
3. Press Cmd+Q.

Then, two copies of unsaved changes dialog appear, and you need to click any button there twice.

This does not happen when using File → Exit menu option. I don't think it's a regression, since it's been there for quite a long time. See #11342.

Can you please tell me what is your keyboard layout?

[Zverikk]

This can be reproduced on a standard American layout, with an unidentified keyboard (Microsoft Natural 4000).

[Don-vip]

OK. Before I report again the bug to Oracle, can you please tell me if the bug is reproducible with this small Java program?

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

public class Bug extends JFrame {

    public Bug() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel panel = new JPanel();
        panel.add(new JLabel("To run on OSX only: Press Cmd-Q once"));
        getContentPane().add(panel);
        AbstractAction action = new AbstractAction() {
                        @Override
                        public void actionPerformed(ActionEvent e) {
                                JOptionPane.showMessageDialog(Bug.this, "Hello", "Hello", 
                                                JOptionPane.INFORMATION_MESSAGE);
                        }
        };
        panel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(
                        KeyStroke.getKeyStroke(KeyEvent.VK_Q, KeyEvent.META_DOWN_MASK), action);
        panel.getActionMap().put(action, action);
        pack();
        }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new Bug().setVisible(true);
            }
        });
    }
}

The action is never called in this program, regardless of how I close it.

[Don-vip]

And if you replace JLabel by JTextField ? The program works on Windows with event CTRL_DOWN_MASK :(

[Zverikk]

No, JTextField doesn't work either.
It works when I replace META_ with CTRL_, so I guess Cmd+Q is processed differently.

[Don-vip]

In 8952/josm:

see #12012 - add log message for shortcut reassignments

[Don-vip]

Can you please launch the new JOSM latest (r8952) and copy/paste the console output when you launch JOSM? Thanks.

[Zverikk]

I can apply patches locally and build josm-custom, btw.

[Don-vip]

Can you please test with JOSM latest? I think it was a bug of JOSM that I have fixed in r12320

[Zverikk]

You did, thanks a lot!
