[jboss-user] [EJB 3.0] - Inheritance - ClassCastException after upgrade to BEA JRocki

Hi all,

I have an entity NaturalPerson extends Person with singe table inheritance. 

@Inheritance(strategy = InheritanceType.SINGLE_TABLE)

There is a defined column 

@DiscriminatorColumn(name = "INHERITANCETYPE", discriminatorType = DiscriminatorType.STRING)

which is edited with the correct value.

After an upgrade of BEA JRockit R26 to R27 a type cast 

  | NaturalPerson n = (NaturalPerson)aPersonOfWhichIamSureItIsANaturalOne;

fails with a CCE (anything with jassist $-s and proxy).
I fixed any typecast for me by using a visitor, but I think this should be fixed.

I use JBoss-4.0.5.GA with build in EJB3.

Thanks and best regards,
