Best library to implement jsonrpc 2.0 in java with bidirectional support

Question

I am in search of a library to implement jsonrpc 2.0 in java with bidirecional support. I have found these two (JJsonRpc, jsonrpc4j) some recommendation of which one is better?

Answer 1

In the end I decided to write my own integration to the api json rpc using

OKHttp for HTTP connections and Jackson Core for fast JSON serialisation / deserialisation
