[Andromda-user] [Spring cartridge] [HibernateOptimisticLockingFailureException]

[wouter.zoons (A. F. <fo...@an...>]

this happens when two different sessions update the same object in their own thread, are you sure you are working single-threadedly ? because Hibernate is able to detect when two sessions in the same thread have access to the same object (it is refused and an exception is thrown)

the optimistic locking exception occurs when you have versioning enabled and the first thread detects another one has already updated the object before it could commit (i.e. the version number has been incremented or the timestamp has been updated)
