The Hibernate manual states that Sessions should be discarded when an exception is thrown:



Does this apply when an attempt to acquire a lock fails?



I'd like to continue using Sessions after lock acquisition failures under a variety of circumstances. The most mundane example is using lock() to do a version check. Same for attempting to acquire a pessimistic lock with NOWAIT.

Come to think of it, I have the same question about Session.get() and Session.load() -- can I continue to use the Session if it throws an exception because no object was found with the specified ID?

Yes, you can reuse the session after an ObjectNotFoundException. I won't rely on it after a lock failure though.

Thanks for the reply.

Does this apply when the "lock" is just a version check?


I use long-lived/disconnect Sessions, and would like to refresh or evict the stale object rather than discarding the entire Session. I understand that there may be other inconsistencies (e.g., stale data) in the Session cache that could bite me later, but that's always a risk with long-lived Sessions.
