      Currently event handlers that interact with transactions and Hibernate entities might run into some issues:

      • the transaction might not be committed until all handling for the event is done
      • in some cases, the entire transaction might be rolled back, even after the event handler completed successfully
      • some events contain references to Hibernate entities, which is troublesome as events might be shared between threads, and these entities might be attached to a closed session

            Lukasz Pater added a comment -

            Events published during a database transaction are now delayed until that transaction commits. If the transaction rolls back, these are never published.

            Event handlers no longer contain Hibernate entities, nor share a session or transaction with the event publishers.
