Comment 2 Jaroslav Tulach 2010-06-29 09:20:07 UTC 
The snaphot shows that AWT thread waits in AbstractDocument.readLock multiple times. There is "Thread-194" which holds writeLock for multiple times (once 1.5s, once 400ms). 

The possible fix would be to wait while "Thread-194" finishes and only then start to render the component. I am not sure who starts the "Thread-194" however, my guess is that this somehow relates to internal HTML browser. Passing there.
Comment 3 Jesse Glick 2010-06-29 13:49:43 UTC 
Is this really the right component? I don't use the embedded browser; the HTML was being rendered by Swing as part of code completion Javadoc.

I got this error using 7.0 beta.

The last report is more than two years old, closing.
