If a frame has no component in its content pane the menus cannot be opened with
their defined mnemonics. So the application cannot be used with keyboard only.

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

public class JDC2 extends JFrame{

	JDC2(String title){
		super(title);
		init();
		setSize(200, 200);
	}
	
	protected void init(){
		JMenuBar menuBar = new JMenuBar();
		JMenu menu = new JMenu("Test");
		menu.setMnemonic('T');
		menu.add(new JMenuItem("Subtest", 's'));
		menuBar.add(menu);
		setJMenuBar(menuBar);

	}
	
	public static void main(String [] args){
		try{
			UIManager.setLookAndFeel(new
com.sun.java.swing.plaf.windows.WindowsLookAndFeel());
			JFrame frame = new JDC2("Mnemonic Test");
			Dimension screenSize =
  Toolkit.getDefaultToolkit().getScreenSize();
			Dimension frameSize = frame.getSize();
			frame.setLocation((screenSize.width - frameSize.width) /
2, (screenSize.height - frameSize.height) / 2);
			frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
			frame.setVisible(true);
		}
