The "OK" button in the JFileChooser does not resond to keyboard accelerator key "ALT+O". The "Update" and "Cancel" buttons react to "ALT+U" and "ALT+C", respectively. Java 1.3.1

Test case:

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

public class JFCTest extends JFrame {

        public JFCTest() {
                JButton j = new JButton("Open");
                this.getContentPane().add(j);
                j.addActionListener(new ActionListener() {
                        public void actionPerformed(ActionEvent ae) {
                                openDialog();
                        }
                });
        }

        private void openDialog() {
            JFileChooser jfc = new JFileChooser();
            jfc.showOpenDialog(this);
        }
        
        public static void main(String args[]) {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (Exception ex) {}
                
                JFCTest j = new JFCTest();
                j.setSize(100,100);
                j.setVisible(true);
        }
}
