Deferring since it is due to an invalid user data case that can be worked around, so isn't stop-ship.

Is anything preventing the patch from being applied to 3.2.3? Any other assistance we can offer to help resolve this bug?

Comment 6 Raghunathan Srinivasan

Mass update: The JSF Tools team is currently focused on performance and deadlock issues in the product. We plan to address other WTP bugs later this month and will review and checkin the patches soon. Thanks for your contribution and understanding.

This appears to have been fixed on 2010/08/24, but not marked fixed. I am now seeing the "invalid resource" message as info in the log, without a thrown exception.
