RecordId annotation does not consider superclasses

Current "RecordID" implementation is using "getDeclaredFields ()" which is returning only fields of current class.
It doesn't not find the "RecordID" when coming from a superclass like this:

class DBObject {
@RecordID
public Integer id;
}
class MyData extends DBObject {
public String firstName;
}

The "Scan" class will not find the inherited "RecordID" in the "MyData" class.
