Yeah, I did. My mistake, I left that out in my code above. There *is* a
@MappedSuperclass annotation on the superclass Identifiable. The precise
stack trace of the exception is as follows; it is at the end of a long
stream of nested exceptions. The exception happens after I attempt to
create a query.
<openjpa-2.0.0-r422266:935683 fatal user error>
org.apache.openjpa.persistence.ArgumentException: Superclass field
"java.lang.Object.id" is mapped in the metadata for subclass
"org.ltmc.eve.dump.inventory.Group", but is not a persistent field.
