The failure is clearly a user error but the message is bad. The message should
say that the type of the argument doesn't match the metadata for the class.
The failing line of code is:
LongLongStringFKRelationship b =
em.find(LongLongStringFKRelationship.class, i);
The correct code is:
LongLongStringFKRelationship b =
em.find(LongLongStringFKRelationship.class, new LongLongStringOid(i));
