> While brainstorming for AVRO-3370, I came across this special case where a type-reference could be considered ambiguous if the SDK is not careful when simplifying inherited namespaces:
> {code:json}
> {
>   "type" : "record",
>   "name" : "ns.int",
>   "fields" : [ 
>     {"name" : "value", "type" : "int"}, 
>     {"name" : "next", "type" : [ "null", "ns.int" ]}
>   ]
> }
> {code}
> In Java, if this code is parsed, it works as expected (as a linked list).
> If the schema is turned to a String using toString(), the namespace is dropped off the last {*}{{ns.int}}{*}, turning it into the primitive. That string can still be parsed into a Schema, but the "round-trip" modifies the schema in an incompatible way.
> That namespace shouldn't be dropped when producing the JSON string representing the Schema in Java.
