I'm not arguing with the ORB's behavour, I'm arguing about the way the transaction service sat on top of the ORB translates that. If a client gets an OBJECT_NOT_EXIST it only knows the tx went away, not what state the tx was in. Assuming rollback is unreasonable - it may just as easily have committed via another thread or a different JVM.
