Hi all !

In a Swing-application I am trying to create a JSpinner with a tooltip,
but the spinner's tooltip never shows up. (My platform is Java 1.4.2_05)
What is wrong with my code? Or is it a bug of JSpinner itself?
Below you find a stripped-down application for reproducing the problem.

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

public class Test
{
 public static void main(String[] args)
 {
   JFrame frame = new JFrame("Test");
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   Container contentPane = frame.getContentPane();
   contentPane.setLayout(new FlowLayout());
   String fontNames[] = {"Courier","Helvetica","Times New Roman"};
   JComboBox nameComboBox = new JComboBox(fontNames);
   JSpinner sizeSpinner = new JSpinner(new SpinnerNumberModel(12,8,36,1));
   nameComboBox.setToolTipText("Font name");  // this tooltip pops up fine
   sizeSpinner.setToolTipText("Font size");   // ..and this does not!!
   contentPane.add(nameComboBox);
   contentPane.add(sizeSpinner);
   frame.pack();
   frame.setVisible(true);
 }
}
