	 * first one's class-loader to construct the proxy class with. This is also the reason why HibernateProxy.class
	 * should be the last one in the order (on JBossAS7 its class-loader will be org.hibernate module's class-
	 * loader, which will not see the classes inside deployed apps.  See HHH-3078
