Description David Strupl 2000-12-05 17:15:57 UTC 
I am not able to reproduce it. But it happened and here goes the thread dump.
I am suspecting DisabledIcon.paintIcon to register an instance of JLabel as an
ImageObserver causing the ImageFetcher thread to freeze. It freezes because
in JLabel's imageUpdate method calls getDisabledIcon which in turn tries to load
disabled icon and blocks the image fetcher thread.
This is quite rare and I am not sure if the given explanation holds. Any idea
welcomed.

Someone should probably contact the JDK team. Who has the best relationship?
Comment 3 David Strupl 2001-02-06 10:45:59 UTC 
DisabledIcon.paintIcon was changed. It should not happen any more.
imageUpdate in JLabel is strange but not registering JLabel as image
observer solves the problem. Marking this one as fixed.
