> (This bug was exposed by MESOS-4184, when serializing docker v1 image
> manifest as protobuf).
> Currently protobuf::parse returns failures when parsing any JSON containing
> JSON::Null. If we have any protobuf field set as `JSON::Null`, any other
> non-repeated field cannot capture their value. For example, assuming we have
> a protobuf message:
> {noformat}
> message Nested {
> optional string str = 1;
> repeated string json_null = 2;
> }
> {noformat}
> If there exists any field containing JSON::Null, like below:
> {noformat}
> {
> \"str\": \"message\",
> \"json_null\": null
> }
> {noformat}
> When we do protobuf::parse, it would return the following failure:
> {noformat}
> Failure parse: Not expecting a JSON null
> {noformat}
