I am trying to do:
- Send request from HttpClient (based on HttpComponents HttpClient 4.5).
- Receive that request in HttpServer (based on HttpComponents HttpCore 4.4.1).
- HttpServer must answer to HttpClient with different HttpStatus codes and string entities as body.
Problem: If HttpServer make answer with status code 200 (or any others, not checked) then it is worked fine and no exceptions on server side. But if server set answer status code 400, then there is IOException on HttpServer has been occured. Description on russian is "Удаленный хост принудительно разорвал существующее подключение", on english i think it is "Client closed connection". Simple one: on status 200 there is no problem, on 400 it is exception occured on server.
Exception string:
