I tried B82 but unfortunately 2 of our projects produce the same ClassCastException in the compiler, so I can't stick with it. I don't have much time to investigate it and obviously I can't submit our entire codebase to the bug parade so I haven't reported it. Here is the trace from the exceptions in case anyone has seen anything similar:-

[apt] An exception has occurred in apt (1.6.0-beta2). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you.
