According to SQE, the problem described in 6458497 still reproducible with jdk 7.0 b07
(however I was unable to reproduce it :( Here is a test which was used to reproduce the
problem.
import java.awt.*;
import javax.swing.*;
public class AltTab {
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(UIManager
.getSystemLookAndFeelClassName());
} catch(Exception e) {
}
JFrame frame = new JFrame("Alt-Tab Frame");
JMenuBar menuBar = new JMenuBar();
frame.setJMenuBar(menuBar);
JMenu fileMenu = new JMenu("File");
char fileMenuMnemonic = 'F';
fileMenu.setMnemonic(fileMenuMnemonic);
menuBar.add(fileMenu);
frame.setSize(100,100);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
