Bug: IconUIResource doesn't paint an animated ImageIcon

Question

I was recently playing with Icons and found that javax.swing.plaf.IconUIResource doesn't paint an ImageIcon that contains an animated GIF. Found the reason in these bug fixes.

From that, I could arrive at a workaround: extend ImageIcon to implement the UIResource marker interface and use this class instead of wrapping an ImageIcon in a IconUIResource. Interestingly, NetBeans autocomplete revealed the existance of sun.swing.ImageIconUIResource which I determined to be a direct subclass of ImageIcon, with two constructors that take an Image and byte[] respectively.
Test SSCCE: import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JOptionPane;
import javax.swing.UIManager;
import javax.swing.plaf.IconUIResource;
import javax.swing.plaf.UIResource;
public class IconUIResourceBug {
  public static void main(String[] args) {
    try {
      URL imageURL = new URL("http://www.smiley-faces.org/smiley-faces/smiley-face-rabbit.gif");
      InputStream is = imageURL.openStream();
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
      int n;
      byte[] data = new byte[1024];
      while ((n = is.read(data, 0, data.length)) != -1) {
        baos.write(data, 0, n);
      baos.flush();
      byte[] bytes = baos.toByteArray();
      ImageIcon imageIcon = new ImageIcon(bytes);
      Icon icon = new IconUIResource(imageIcon);
      UIManager.put("OptionPane.errorIcon", icon);
      JOptionPane.showMessageDialog(null, "javax.swing.plaf.IconUIResource", "Icon not shown",
              JOptionPane.ERROR_MESSAGE);
      icon = new ImageIconUIResource(bytes);
      UIManager.put("OptionPane.errorIcon", icon);
      JOptionPane.showMessageDialog(null, "ImageIconUIResource", "Icon shown",
              JOptionPane.ERROR_MESSAGE);
      icon = new sun.swing.ImageIconUIResource(bytes);
      UIManager.put("OptionPane.errorIcon", icon);
      JOptionPane.showMessageDialog(null, "sun.swing.ImageIconUIResource", "Icon shown",
              JOptionPane.ERROR_MESSAGE);
    } catch (MalformedURLException ex) {
      ex.printStackTrace();
    } catch (IOException ex) {
      ex.printStackTrace();
class ImageIconUIResource extends ImageIcon implements UIResource {
  public ImageIconUIResource(byte[] bytes) {
    super(bytes);
}I can't see any alternative fix for the one carried out in response to the quoted bug reports, so have held off on making a bug report. Any ideas?
Thanks for reading, Darryl
I'm also posting this to JavaRanch for wider discussion, and shall post the link here as soon as possible. I'll also keep both threads updated with all significant suggestions received.

Answer 1

Animated gif is working fine for me.
You can check the delay time between the images in the gif, to see that it's not too short.
Here's a simple example:import java.net.URL;
import javax.imageio.ImageIO;
import javax.imageio.stream.ImageInputStream;
import javax.swing.ImageIcon;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
import com.sun.imageio.plugins.gif.GIFImageMetadata;
import com.sun.imageio.plugins.gif.GIFImageReader;
public class AnimatedGifTest {
    public static void main(String[] args) {
        try {
            JFrame frame = new JFrame();
            frame.setDefaultCloseOperation(JDialog.EXIT_ON_CLOSE);
            URL url = new URL("http://www.gifanimations.com/action/SaveImage?path=/Image/Animations/Cartoons/~TS1176984655857/Bart_Simpson_2.gif");
            frame.add(new JLabel(new ImageIcon(url)));
            frame.pack();
            frame.setVisible(true);
            // Read the delay time for the first frame in the animated gif
            GIFImageReader reader = (GIFImageReader) ImageIO.getImageReadersByFormatName("GIF").next();
            ImageInputStream iis = ImageIO.createImageInputStream(url.openStream());
            reader.setInput(iis);
            GIFImageMetadata md = (GIFImageMetadata) reader.getImageMetadata(0);           
            System.out.println("Time Delay = " + md.delayTime);
            reader.dispose();
            iis.close();
        } catch (Exception e) {e.printStackTrace();}
}
