Both methods focusGained and focusLost methods failed reporting when JToolBar was in focus.

Code snippet:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class FrameDemo extends JFrame implements FocusListener {
    public FrameDemo() {
        setSize(300, 300);
        
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
        
        //adding JToolBar
        JToolBar toolBar = new JToolBar();
        toolBar.addFocusListener(this);
        
        getContentPane().add(toolBar, BorderLayout.CENTER);
    }
    public static void main(String s[]) {
      FrameDemo fd = new FrameDemo();
      
      fd.pack();
      fd.setVisible(true);
    }
    
    public void focusGained(FocusEvent e) {
      System.out.println(e.getComponent());
    }
    
    public void focusLost(FocusEvent e) {
      System.out.println(e.getComponent());
    }
}
