Scott Marlow commented on AS7-3402:
-----------------------------------

Regarding my idea for squashing notserializable exceptions (into a string representation), it might be too expensive to attempt serializing very large exception instances (like a OptimisticLockException that references a very large entity) to determine that they are not serializable.  

Perhaps we could make a Hibernate change to not pass the entity into the OptimisticLockException.  I wouldn't want to do that since some applications could depend on getting the entity from the OptimisticLockException.

Choosing between the slower performance of serializing very large OptimisticLockException versus losing the functionality of throwing fully filled in OptimisticLockException (include the entity).  Taking the performance hit is probably better.

The third option, is to let the NSE or CNFE happen (just fix the stream being closed issue as others are saying).  As long as the exception is logged on the server side, that is not horrible.
