Major 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()));
