--------------------------------
Attachment: OPENJPA-2163.trunk.patch
> Lifecycle event callback occurs more often than expect
> ------------------------------------------------------
>
> Key: OPENJPA-2163
> URL: https://issues.apache.org/jira/browse/OPENJPA-2163
> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 2.0.3, 2.1.2, 2.3.0, 2.2.1
> Reporter: Albert Lee
> Assignee: Albert Lee
> Fix For: 2.3.0, 2.2.1
>
> Attachments: OPENJPA-2163.trunk.patch
>
>
> A problem was uncovered in a scenario where multiple EntityManager instances
> created from the same EntityManagerFactory, and each instance is initialized
> with a new instance of a LifecycleListener instance, i.e.
> final EntityManager em = factory.createEntityManager();
> final EntityManager em2 = factory.createEntityManager();
> ...
> MyLifecycleListener l1 = new MyLifecycleListener();
> MyLifecycleListener l2 = new MyLifecycleListener();
> ...
> ((OpenJPAEntityManagerSPI)em).addLifecycleListener(l1, null);
> ((OpenJPAEntityManagerSPI)em2).addLifecycleListener(l2, null);
> When life cycle event occurs for a specific entity manager, all the listeners
> created under the emf are being invoked. The expected behavior is only the
> listener registered in the em from which the life cycle events are related
> should be called.
