        Key: HB-482
    Summary: NPE in net.sf.hibernate.impl.SessionImpl
       Type: Bug

Description:
I get a NPE in the following method in
if (!ce.initialized)

It happens sporadically but rather often.

/**
	 * called by a collection that wants to initialize itself
	 */
	public void initialize(PersistentCollection collection, boolean writing) throws HibernateException {

		CollectionEntry ce = getCollectionEntry(collection);

		if ( !ce.initialized ) {

			if ( log.isTraceEnabled() ) log.trace( "initializing collection " + MessageHelper.infoString(ce.loadedPersister, ce.loadedKey) );

			try {
				ce.loadedPersister.getInitializer().initialize(ce.loadedKey, this);
			}
			catch (SQLException sqle) {
				throw new JDBCException("SQLException initializing collection", sqle);
			}

		}
	}
