c++ server and java client communications issue

Hello. I try write gRPC communication with java client and c++ server on linux. But i have exception (below) in client when it runs RPC procedure. Logs shows that server processed request, sended answer and continues its work. For test i wrote same client on c++ and same server on java. All communication versions works. And only client(java) with server(c++) failed. I hope you can help me. Thanks.

Ok. I will wait a solving. Thank you.

We’ve seen the problem go away on integration tests as well. I’m not fully certain what change caused it to be introduced or fixed, but it seems resolved at this point.
