CLONE - EJB2 CMP all entities are synchronized with the database if <EntityHome>.findByPrimaryKey(...) is called ---------------------------------------------------------------------------------------------------------------- Key: AS7-6326 URL: https://issues.jboss.org/browse/AS7-6326 Project: Application Server 7 Issue Type: Bug Affects Versions: 7.1.3.Final (EAP) Reporter: Wolf-Dieter Fink Assignee: Wolf-Dieter Fink This is a different behavior to former AS versions and a huge performance issue. From the EJB spec the entities must be flushed due to have the correct result of the invoked finder. ejbFindByPrimaryKey() is special as there is no need to flush other instances. It is ensured that the entity is found nevertheless whether it is changed or not as the 'cache' is evaluated first.
