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
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.
