> I think we should add guards to MediatorImpl.mediate() so that:
> - We don't do the introspectType(source) if 'source' is null
> - We simply return 'source' if 'targetDataType' is null
> While, for some methods, we might put the burden on the caller to check, this method is already one that can handle nulls for certain objs, and we want to possibly allow transforming a null
> 'source', so it seems better to make the mediate() method itself more robust.
> I'll attach a patch.
