In 1.4.2 it is more easily reproducible because of the fix for 4765331 EditorPane editing: Ctrl-A + Delete on wrapped HTML throws BadLocationException Part 1. This is what needed to make bug 4822422 to occur: If the same image is used for background and for <img> tag deadlock might happen. <technical details> It happens because the same ImageFetcher is used for loading the same image. Background image loading initiated by parsing thread. Image for <img> tag loading initiated by view hierarchy building thread. Parsing thread waits until the image is loaded completely holding the write lock for the document. When new portion of the image is available ImageObserver.imageUpdate method is called for ever ImageObserver which is interested in this image. ImageView.ImageHandler.imageUpdate tries to get readlock for the document in some cases. We can not get the readlock when some other thread has the write lock. ImageFetcher for this image holds. At some point we need to get the readlock from event dispatching thread and this thread holds as well. Now we have imageFetcher, parsing thread and event dispatching thread on hold. We should not stop in imageUpdate in any case. In this case this was a typo in ImageView.java I would say. We are getting readlock in imageFetcher thread but accessing the document in event dispatching thread. Instead we should get the lock in the same thread we want to access the document. </techincal details> To fix this we need modify ImageView.java The code change less than 20 lines. The risk is minimal. The code would work the way it was supposed to be working. <technical details> * ImageView.java 2003/02/28 15:03:01 1.1 --- ImageView.java 2003/03/12 20:38:15 ************* * 869,880 **** / private void safePreferenceChanged() { if (SwingUtilities.isEventDispatchThread()) { preferenceChanged(null, true, true); } else { !
