How to make scrollpane scroll with textfield focus

Question

I have a JScrollPane that contains a JPanel with a grid of Labels and JTextFields for data entry. When I tab through the textfields down the panel - reaching fields that are out of view, the scroll pane does scroll down fields with the cursor - keeping the cursor in view.
Is there a way to do this? I've tried some things, but I have not been able to get this working.

here you go..
package com.u2d.focustest;
import javax.swing.*;
import java.awt.*;
import java.awt.event.FocusEvent;
import java.awt.event.FocusAdapter;
public class KeepCursorInView extends JFrame
   public KeepCursorInView()
      JPanel contentPane = (JPanel) getContentPane();
      JPanel fieldPanel = new JPanel(new GridLayout(12, 3));
      JScrollPane scrollPane = new JScrollPane(fieldPanel);
      contentPane.add(scrollPane, BorderLayout.CENTER);
      for (int i=0; i<36; i++)
         addField(fieldPanel);
   private void addField(final JPanel panel)
      final JTextField tf = new JTextField();
      panel.add(tf);
      tf.addFocusListener(new FocusAdapter()
         public void focusGained(FocusEvent e)
            Rectangle bounds = tf.getBounds();
            panel.scrollRectToVisible(bounds);
   public static void main(String[] args)
      JFrame f = new KeepCursorInView();
      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      f.setBounds(100,100,400,400);
      f.setVisible(true);
}
