While the applet below is loading (which should take a long time...the jar file is very large), an animated GIF should be displayed. If it is, the test has passed; otherwise, it has failed.
You might want to clear the "huge.jar" resource out of your deployment cache afterward, as it is roughly 20 MB of junk. Also, if you do not clear it out afterward, this test will of course not work any more since the applet will load nearly instantaneously.
