[jboss-user] [EJB 3.0] - ClassCastException in the InvokeRemoteInterceptor

[mindflyer]

Client application lookups SLSB in the JNDI and invokes its method. If SLSB throws exception (in this example - DAOException),  I see on the client side ClassCastException.

Caused by: java.lang.ClassCastException: net.uk.topdog.td2.common.dao.DAOException

I saw ClassCastException for EJBException also.
And ClassCastException for NotFoundInDispatcherException if I used clustered SLSB.

My SessionBean :

@Stateless(name = "UnTypedEmfDAORemoteSessionBean")
@Remote(UnTypedEmfSerializableDAO.class)
@Interceptors({EmfPreparerForSerialization.class})
public class UnTypedEmfDAORemoteSessionBean implements UnTypedEmfSerializableDAO { ... }

I use JBoss 4.0.5.GA with jboss-EJB-3.0_RC9_Patch_1 now.
Earlier I used JBoss 4.0.4.GA with EJB 3.0 RC7 and didn't see ClassCastException.
