> {{ReflectData.AllowNulls}} will always create nullable types, even if the
> reflected object has primitive fields. When assigning a null to a primitive
> field, Java always throws a {{NullPointerException}}. I think the right thing
> to do is to allow nulls for any {{Object}} and return required schemas for
> primitive types.
