i had already extend jackson protobuf to support protobuf3 map feature. based on jackson 2.9.6, because we are using 2.9.6 but jackson 2.9.6 already released. even i raise a PR for this and jackson will merge it, we can not use it directly or must wait for next release.
but we must start new task based on this feature right now. so how to resolve the confliction?
