> This is a patch copied from Hibernate 3.6.3 and tracked here: https://issues.jboss.org/browse/JBPAPP-3737
> ==========
>  In a stateless session, queries load objects in a two-phase process: in the first phase, a temporary persistence context is populated with empty objects; in the second phase, the objects' member data is read from the database. If an object contains an association or a collection, the query performs a recursive call to the session's get() method. This clears the temporary persistence context.
> If the parent object contained any other associations to be read as part of the second phase, Hibernate threw an assertion because the associations cannot be found in the persistence context.
> This has been fixed by introducing a new method: <literal>org.hibernate.engine.PersistenceContext.isLoadFinished()</literal>. This method tells StatelessSession when to clean the temporary persistence context.
