Description

In this excerpt from ClassMetaData, we are seeking getter and setter in an identity class. We should be seeking getter and setter with type of Entity class's *key*, not type of Entity class per se. The getter code refers to "c", which was earlier set to the correct object id field type. But the setter-seeking code refers incorrectly to "fmds[i].getDeclaredType()". This is a show-stopper, as it makes OpenJPA manual section 3.2 un-implementable.

if (m == null || !m.getReturnType().isAssignableFrom(c))
                    throw new MetaDataException(_loc.get("invalid-id",
                        _type, fmds[i].getName()));
                m = Reflection.findSetter(oid, fmds[i].getName(),
                    fmds[i].getDeclaredType(), false);
                if (m == null || m.getReturnType() != void.class)
                    throw new MetaDataException(_loc.get("invalid-id",
                        _type, fmds[i].getName()));
