Jetty version(s)
10+

Description
In case of HTTP CONNECT tunnelling with HTTP/1.1, the upstream server may close the connection immediately.
In such case, there is a race condition trying to write the 200 OK (for a successful tunnel establishment) and closing the connection (because the server closed it immediately).

The client may not see the 200 OK that it is supposed to see, and just see the connection closed.
