Hi,

I receive an exception (see below) on the cleint when loading a Entity that has unitialized properties after moving to EJB3RC4-PFD. This works fine when i initialize all my properties in the Session Bean. It also worked fine with JBoss 4.0.3RC2 and EJB3.0RC3.

Has anything changed regarding the Entity class requirements? I couldn't find anything in migrating part on the wiki.

thanks a lot in advance!

Hibernate version:

JBoss 4.0.3SP1
JBoss EJB3.0RC4-PFD

Mapping documents:

Code:

@Entity
public class AankoopAfspraken extends BaseEntity {
}

@MappedSuperclass
public abstract class BaseEntity extends Model implements Serializable {
}



Full stack trace of any exception that occurs:

Code:
[12:16:42,015] [ERROR] [SocketClientInvoker:274] - Got marshalling exception, exiting
java.lang.ClassCastException: cannot assign instance of org.hibernate.proxy.SerializableProxy to field be.profitplus.entities.contact.CommercieelContact.aankoopAfspraken of type be.profitplus.entities.contact.AankoopAfspraken in instance of be.profitplus.entities.contact.CommercieelContact

CGLIB change? To which version?
4.0.4RC1 comes with the same same cglib version as 4.0.3SP1: cglib-2.1.2jboss.jar
