persistence-xml just contains entity class definitions, and datasource
specific properties. EJB 3.0 spec says that when entitymanager or query flush
mode is AUTO then, all queries after that will contain new values. But I am not
sure this is in the same entity manager, because in method1 and method2, I use
two different entitymanager.
