Hibernate StaleObjectStateException during Concurr

I am using Hibernate 3.5.2 and Spring Core 3.0.1 in a Java J2EE Web Application. I am getting a StaleObjectStateExcpetion when separate users are updating the same record concurrently. The transactions are managed by javax.persistence.EntityManager. Here are the steps I take to create the issue.

  1. User1 logs into the application
  2. User2 logs into the application
  3. User1 starts to edit recordA
  4. User2 starts to edit recordA
  5. User1 saves recordA
  6. User2 saves recordA
  7. An org.hibernate.StaleObjectStateException is thrown (see below)

I have read that this is caused by a difference between the updated version number in the database and the version number currently in memory for that particular entity. However, when I try to find the current version number in the database using a query or by using the EntityManager.find() method to get the latest information from the database, I find no difference in the version numbers. I have also tried to merge changes between the old entity and the new entity both manually and using the entityManager.merge(object) method with no luck. Any ideas on how to fix this issue?

Here is how optimistic locking works:

  1. User1 starts to edit recordA - recordA is loaded from the database with version V
  2. User2 starts to edit recordA - recordA is loaded from the database with version V - exactly the same as above

  3. User1 saves recordA - recordA is saved but Hibernate transparently adds:

    UPDATE
...
SET V = V + 1
WHERE version = V

    At this point Hibernate verifies whether the number of modified records returned from the database is exactly 1. If the query modified 0 records it means that the WHERE version = V clause was not met. In this case everything went fine and the version was set to V + 1 (important!)

  4. User2 saves recordA - Hibernate does exactly the same thing, still having the old V version number in memory. Unfortunately in this case the WHERE version = V condition is not met since version is now V + 1. The query returns 0 modified records which makes Hibernate believe (correctly) that the record was modified in the meantime. This is what the exception says.

So what can you do about it? Simply catch the exception and:

  1. Repeat the whole transaction, but reload the entity (with new version V + 1) so that after updating you won't loose the last change

  2. Or inform the user that the object was modified in the meantime so she can inspect the new version.

Both solutions are fine depending on your use case.
