> We observed an issue where with a httpcore-nio server timeout scenario, the server sends a FINACK to the client and if the client sends a close_notify alert, the server is immediately sending a RESET and closing the connection. Ideally, the server should also send a close_notify and terminate the connection gracefully. This issue is observed with only the clients which send close_notify for a server FINACK. The below attached is a TCP capture during the timeout scenario (server port: 8253). The server uses the latest 4.4.16 httpcore-nio library.

> Is there any way to avoid this scenario and send a close_notify from the server as well to terminate the connection gracefully?
> PS: I am currently working on a simple reproducer to attach here, and I'll attach it as soon as possible.
