I am currently persisting an interface, Auditable. This interface is implemented by AbstractAuditEvent and this is in turn subclassed by AuditEvent. The mapping file is Auditable.hbm.xml and I create instances of AuditEvent and persist using this mapping.

This worked fine when I was using sdk 1.3/OC4J 9, but now I have moved to sdk 1.4 /OC4J 10g it fails like so:

Any ideas? other hibernate mappings seem to work OK and I have not changed anything except the SDK/app server versions.
