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.
