Re: [protobuf] proto3 backward compatibility problem

I knew it, because yarn depends on proto2 but my lib depends on proto3. The reason is that proto3 runtime doesn't keep backward compatibility. The problem can be reproduced if set option java_generate_equals_and_hash = true with proto2. I hope msg with proto2 still work with proto3 jar since
