Loader.initializeEntitiesAndCollections() does not guarantee correct behavior of Lifecycle.onLoad()
---------------------------------------------------------------------------------------------------

                 Key: HHH-3894
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3894
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.1
            Reporter: Michael Papadopoulos


Consider lines 871-879 of org.hibernate.loader.Loader (method initializeEntitiesAndCollections()) :

		if ( hydratedObjects!=null ) {
			int hydratedObjectsSize = hydratedObjects.size();
			if ( log.isTraceEnabled() ) {
				log.trace( "total objects hydrated: " + hydratedObjectsSize );
			}
			for ( int i = 0; i < hydratedObjectsSize; i++ ) {
				TwoPhaseLoad.initializeEntity( hydratedObjects.get(i), readOnly, session, pre, post );
			}
		}

It is possible that hydratedObjects.get(1) is an entity contained in hydratedObjects.get(0). If hydratedObjects.get(0) implements org.hibernate.classic.Lifecycle, its onLoad() method will be called before the contained entity hydratedObjects.get(1) is initialized, thus breaking the contract of onLoad() (i.e. that onLoad() is called after the entity is loaded; in our case hydratedObjects.get(0) will not be fully loaded yet, since one of its properties will not have been initialized yet).
