-------------------------------------------
Summary: Connection resets during timeouts
Key: HTTPCORE-740
URL: https://issues.apache.org/jira/browse/HTTPCORE-740
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore NIO
Affects Versions: 4.4.16
Reporter: Arunan Sugunakumar
Attachments: Screenshot 2023-04-18 at 07.53.12.png
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.
