/**
 * 
 * All annotated properties should have this class as base class.
 * 
 * 
 * The delegation seems to be unnecessary at first glance, but it has the advantage that we do not have decide whether we extend from FieldProperty or
 * MethodProperty. Or we could extend from GenericProperty, but then we would have to deal with the generic type detection on our own.
