Java SE (Java Platform, Standard Edition)

It seems the QUESTION_MESSAGE icon when running on my Mac OS X box is either missing or has some other problem.

Let me start by describing my environment. I'm currently using Mac OS X 10.5.6. Under About This Mac, it shows I have JavaVM 12.2.2 installed. Given the version difference from PC, I wasn't entirely sure if Eclipse was using the same VM. Eclipse shows the selected Installed JRE as JVM 1.5.0 (MacOS X Default). However, 12.2.2 is the version that is shown in the default About window of my Swing applications launched from Eclipse, so I think it probably is. I don't quite understand how the versions work on Mac. If I type "java -version" from the terminal it shows version 1.5.0_16-b06-284.

Now on to the problem. The QUESTION_MESSAGE icon doesn't seem to match all the other JOptionPane icons for starters. Further indication of a problem comes when I set the system property to give my app a proper name in the application drop down menu, at which time I also get an error in the console and the dialog appears with no icon at all.

The error I get when the system property is set is as follows:

2009-02-25 20:03:49.053 java[6481:10b] *** CPerformer: ignoring exception 'Can't cache image' raised during perform of selector 'getDockIconImage:' on target '<ApplicationDelegate: 0x82def0>' with args '<>'

Can anyone else with Mac OS X try this out and see what the results are? Below is a sample app that demonstrates the problem on my machine.

import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.SwingUtilities;

public class IconFailure {

	public static void main(String[] args) {
		// if property is set, no icon is rendered for question message in JOptionPane
		// if property is not set, a generic icon (dissimilar from the other JOptionPane icons)
		// is rendered for question message in JOptionPane
		System.setProperty("com.apple.mrj.application.apple.menu.about.name", "Icon Failure Test");
		SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				launch();
			}
		});
	}
	
	private static void launch() {
		JFrame frame = new JFrame("Icon Failure");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(200, 200);
		frame.setLocationRelativeTo(null);
		frame.setVisible(true);
		JOptionPane.showConfirmDialog(frame, 
				"Does the question icon appear?", 
				"Icon Failure Test", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE);
	}
}

Thanks,

Scott
