Got this one often since upgrading to 7.1.2. A writing thread waits trying to acquire the lock in ClonableEditorSupport.prepareDocument while the AWT event thread, which locked the ClonableEditorSupport in ClonableEditorSupport.closeDocument, is trying to acquire the read lock. Let me know if full dump is needed.

This should be a dup of issue #207571 fixed in trunk and NB 7.2 Beta. The CES.close() now acquires readlock first prior CES.getLock(). *** This bug has been marked as a duplicate of bug 207571 ***
