Forum post http://community.jboss.org/message/625679#625679, describes a possible regression (from Hibernate 3.3.2.GA to whichever version of Hibernate 4.0.0 they are using.) From my response: "For the Hibernate classloader issue, I'm not sure about that one. If org.hibernate.engine.jdbc.ClobProxy is used on application classes, then it looks correct for application classes. If that ClobProxy is always used for Hibernate classes, I think it should always use the ClobImplementer.class.getClassLoader() class loader. " Also, should I push for an AS7 test case or should we push them over to create a Hibernate test case? If someone more in the know, wants to respond directly, all the better. ;) Thoughts? Scott
