java version "1.4.0-beta"

Java HotSpot(TM) Client VM (build 1.4.0-beta-b65, mixed mode)

Under JDK 1.4 beta, the ImageIcon assigned to a JButton does NOT display if you
call setPreferredSize() on the JButton. Under JDK 1.3.0_02, the icon displayed
fine, regardless whether you called setPreferredSize() or not.

I've given the JDK 1.4 version information above.
For JDK 1.3.0_02, the version info is:
java version "1.3.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_02)
Java HotSpot(TM) Client VM (build 1.3.0_02, mixed mode)

Here is the complete source code for a simple Java application that
demonstrates the problem.

// AppBug.java

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class AppBug
{
JButton _buttonDeleteOne;
JButton _buttonDeleteTwo;
ImageIcon _iconDelete;
JFrame _mainFrame;
JPanel _mainPanel;

public static void main(String args[])
{
try
{
AppBug myself = new AppBug();
myself.doit(args);
}
catch(Exception exception)
{
System.out.println(exception.getMessage());
exception.printStackTrace();
}
}

public void doit(String args[])
{
_iconDelete = new ImageIcon("Delete16.gif");

_mainFrame = new JFrame("Demonstrate JButton/ImageIcon Bug");
_mainPanel = new JPanel();
_mainFrame.setContentPane(_mainPanel);
_mainPanel.setLayout(new FlowLayout());

// Handle termination of the app
WindowListener wl = new WindowAdapter()
{
public void windowClosing(WindowEvent ee) { System.exit
(0); }
};
_mainFrame.addWindowListener(wl);

// This button/icon does NOT display correctly
// But, if you comment out the call to setPreferredSize, it
WILL display correctly.
_buttonDeleteOne = new JButton(_iconDelete);
_buttonDeleteOne.setPreferredSize(new Dimension
(_iconDelete.getIconWidth()+10,_iconDelete.getIconHeight()+10));
_mainPanel.add(_buttonDeleteOne);

// This button/icon displays correctly
_buttonDeleteTwo = new JButton(_iconDelete);
_mainPanel.add(_buttonDeleteTwo);

_mainFrame.pack();
_mainFrame.setVisible(true);
}
}
