Focus with JComboBox? HELP!!!

Question

How do you set the focus for a JComboBox? When I use the addFocusListener on a JComboBox it does NOT gain or lose any focus. But when applied to a JButton you'll see it gain and lose focus. Is this a bug in java for the JComboBox?
Here's an example of the usage
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Test extends JApplet {
MyFocusListener focuslistener = new MyFocusListener();
JButton button_1 = new JButton("regular button 1");     
JComboBox combo_2 = new JComboBox(new Object[] { "item1", "item2" } );
     public void init() {
          Container contentPane = getContentPane();
          combo_2.setNextFocusableComponent(button_1);
          button_1.addFocusListener(focuslistener);
combo_2.addFocusListener(focuslistener); //<--------- Add listener here
          contentPane.setLayout(new FlowLayout());
          contentPane.add(button_1);
          contentPane.add(combo_2);
class MyFocusListener implements FocusListener
          public void focusGained(FocusEvent e)
               Object object = e.getSource();
               System.out.println("OBJECT: " + object);          
          public void focusLost(FocusEvent e)
          System.out.println("Focus lost" + e);

This is a quick hack to the focuslistener added to a JComboBox. I noticed that inorder to obtain some focus on a JComboBox you must requestFocus on it. Therefore what I do is I requestFocus right after the button has lost focus. Might not be the best thing to do but it's a quick hack.
Code listed below.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Test extends JApplet {
JButton button_1 = new JButton("regular button 1");     
JComboBox combo_2 = new JComboBox(new Object[] { "item1", "item2" } );
MyFocusListener focuslistener = new MyFocusListener();
MyComboListener combolistener = new MyComboListener();
     public void init() {
          Container contentPane = getContentPane();
          combo_2.setNextFocusableComponent(button_1);
button_1.addFocusListener(focuslistener);
combo_2.addFocusListener(combolistener);
          contentPane.setLayout(new FlowLayout());
          contentPane.add(button_1);
          contentPane.add(combo_2);
button_1.requestFocus();
class MyFocusListener implements FocusListener
          public void focusGained(FocusEvent e)
               Object object = e.getSource();
               System.out.println("Button gained Focus");          
          public void focusLost(FocusEvent e)
          System.out.println("Button lost Focus");
combo_2.requestFocus(); //<------------ This is the trick
class MyComboListener implements FocusListener
public void focusGained(FocusEvent e)
               Object object = e.getSource();
               System.out.println("COMBO gained Focus");          
          public void focusLost(FocusEvent e)
          System.out.println("COMBO lost Focus");
}
