> In some cases Hibernate may returns classes, enhanced by CGLib. But if then we will try to get Class MetaData for such classes - it will be failed. For example:
> Object obj = getObjectFrom Hibernate(); //here CGLib enhanced object is returned
> ClassMetaData metaData = sessionFactory.getClassMetaData(obj.getClass());
> //even we just get class from hibernate and it's class supported by Hibernate - we will get here NULL.
> Simple Solution is to check before getting name from class:
> 	public ClassMetadata getClassMetadata(Class persistentClass) throws HibernateException {
>                 Class fixedClass = persistentClass;
> 		if (net.sf.cglib.proxy.Enhancer.isEnhanced(persistentClass)) {
> 			// try to get class itself
> 			fixedClass = valueClass.getSuperclass();
> 		}
> 		return getClassMetadata( fixedClass.getName() );
> 	}
> but not sure it is really correct fix
