JDK-6959569 - need automated testcase for custom progress bar
Description

The following SQE testcase demonstrates this problem:

Comments
EVALUATION The problem is due to at the end of custom progress, the custom progress code made a call into javascript which signals it's fine to perform a javascript to java call into the applet. However, at that moment, the applet instance hasn't been created yet and resulting throwing an exception during the handling of that call. A fix is to treat the custom progress java to javascript call specially without allowing javascript to java call until the applet is ready.
