So it looks like someone is modifing the document outside of the update manager thread. The exception is happening in the dirty region management - the repaint is trying to collect the dirty regions (from the update manager thread) and someone has undoubtably added a new dirty region to the 'list' - which means that someone modified the rendering tree outside of the update manager thread.
Unfortunately the thread that has the exception is the 'good thread' not the 'bad thread'. You might try adding code to the UpdateTracker to print a stack trace if it is called from outside the UpdateManager thread (specifcally the changeStarted method).

Can you provide stack traces? I'm surprised to see this as the UpdateManager is supposed to be thread safe.
Sure, here's my jws.log. Sorry for all the extraneous junk, but I didn't want to remove anything potentially useful from the output. Note that this is with invokeLater. Also the later exceptions can probably be ignored- after the ConcurrentModificationException the app is hopelessly confused.
Thanks again for your continued assistance with this.
