Hi Petr,
Have you verified that if someone draws an animated GIF and then later
returns false from the observer that the associated ImageLoader thread
goes away? I think the dispose() method had a side effect of allowing
the thread to go away and if you don't call it then the ImageLoader
threads that serve the displayers of an animated GIF may run forever
once triggered...

Hello, AWT and 2D teams.
Please review the fix for the issue:

The problem:
In AWT we use a MediaTracker to wait for the tray icon loading. However, if the
TrayIcon is an animated gif the following happen:
The MediaTracker installs an ImageObserver to an image and starts loading.
After the first frame is loaded (and it's really all we need)
the media tracker correctly exits and removes it's ImageObserver. And as it's
the only observer the checkConsumption is called in an
ImageRepresentation. As the availinfo is just FRAMEBITS the successfully loaded
frame was immediately disposed and AWT failed
to draw a tray icon.
With best regards. Petr.
