Imports

Subclass of ProtobufMessageConverter for use with the official "com.google.protobuf:protobuf-java-util" library for JSON support.

Most importantly, this class allows for custom JSON parser and printer configurations through the JsonFormat utility. If no special parser or printer configuration is given, default variants will be used instead.

Requires Protobuf 3.x and "com.google.protobuf:protobuf-java-util" 3.x, with 3.3 or higher recommended.
