Here is the test case:
import java.awt.*;
import javax.swing.*;

public class Test extends JFrame {
    public static void main(String[] args) {
        new Test();
    }
    public Test() {
        super("Test for mnemonics");
        getContentPane().setLayout(new FlowLayout());
        JButton b = new JButton("press");
        getContentPane().add(b);
        b = new JButton("press 2");
        getContentPane().add(b);
        pack();
        setVisible(true);
        try {
            Thread.sleep(1000);
        } catch (Exception e) {
        }
        b.requestFocus();
        getContentPane().remove(b);
    }
}

Compile it and run. You will see that frame has one button and no
visible focus owner. But in fact there is a focus owner - it is
component which is not currently in a frame, it has isShowing() ==
false. In this case, with 1.4.1, mnemonics doesn't work.

>From documentation it is not stated that the program above does
anything wrong but we see two problems - mnemonics doesn't work and
focus owner is actually not isShowing() - and these problems should be
solved.
