[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2437) SessionFactoryImpl.getClassMetadata method is not supported CGLib enhanced classes

SessionFactoryImpl.getClassMetadata method is not supported CGLib enhanced classes ---------------------------------------------------------------------------------- Key: HHH-2437 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2437 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1, 3.2.2 Reporter: Alexey Kakunin 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 -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
