Scroll menu out of control problem

Question

Guys
I have created a scroll menu, everything seems ok except when you click on the arrows, it never stops. I tried everything but can not find which component gets the event. Any suggestion will be appreciated.
Thanks
import javax.swing.JList;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JScrollPane;
import javax.swing.WindowConstants;
public class NewJFrame extends javax.swing.JFrame {
     private JMenuBar menuBar;
     private JMenu menu1;
     public static void main(String[] args) {
          NewJFrame inst = new NewJFrame();
          inst.setVisible(true);
     public NewJFrame() {
          super();
          initGUI();
     private void initGUI() {
          try {
               setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
               String[] petStrings = { "Bird", "Cat", "Dog", "Rabbit", "Pig",
                         "Fish", "Horse", "Cow", "Bee", "Skunk" };
               JList list = new JList(petStrings);
               JScrollPane scrollPane = new JScrollPane(list);
               menuBar = new JMenuBar();
               setJMenuBar(menuBar);
               menu1 = new JMenu();
               menuBar.add(menu1);
               menu1.setText("menu1");
               menu1.add(scrollPane);
               pack();
               setSize(400, 300);
          } catch (Exception e) {
               e.printStackTrace();
}

Works fine on JDK1.4.2 on XP as well.
I don't know why you would be having a problem with JDK1.5. Try deleting all your .class files. Maybe you have a garbage class file lying around that is causing problems.
