Description Jan Stola 2008-03-13 15:33:23 UTC 
Try to assign an animated GIF to some label or button. The GIF will not be animated in the design time. It will be 
animated in run-time only.
Comment 1 Jan Stola 2008-03-13 15:39:52 UTC 
There are (at least) 2 reasons why the icon is not animated.

The first reason is usage of ImageIO.read() in IconEditor. Usage of this method avoids unneeded caching (see issue 
110609 for a test-case). This method returns icons that are not animated. Compare
    label.setIcon(new ImageIcon(ImageIO.read(new java.net.URL(url))));
with
    label.setIcon(new ImageIcon(new java.net.URL(url)));

The second reason is in the way how are ImageIcons serialized (e.g. cloned from model to view). When an ImageIcon for 
animated GIF is serialized and restored then in becomes static (e.g. not animated). Try

    ImageIcon icon = new ImageIcon(new java.net.URL(url));
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    ObjectOutputStream oos = new ObjectOutputStream(bos);
    oos.writeObject(icon);
    oos.close();
    icon = (ImageIcon)new ObjectInputStream(new ByteArrayInputStream(bos.toByteArray())).readObject();
    label.setIcon(icon);

Hence, it is not worth the effort to fix this issue.
