This bug should also affect any response that
[{{MessageSupport#canHaveResponseBody}}|https://github.com/apache/httpcomponents-core/blob/master/httpcore5/src/main/java/org/apache/hc/core5/http/message/MessageSupport.java#L175-L186]
thinks shouldn't have a body.
edit: confirmed it affects the CONNECT case – my test originally only used
methods defined in SimpleHttpRequests, which understandably lacks a CONNECT
option.

> HttpClient5 double-closes IOSessions for HTTP/1.1 HEAD requests
> ---------------------------------------------------------------
>
> Key: HTTPCLIENT-2017
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2017
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Reporter: Richard Hernandez
> Priority: Major
>
> HttpClient5 consistently fails HEAD requests that have the "Connection:
> close" header on the response because the runtime always attempts to close
> the IOSession handling the connection twice. The second close triggers a
> ConnectionClosedException, causing the request to fail.
> For some reason, this only affects HEAD requests. All other HTTP methods work
> fine.
> I don't have a repro that I can share yet, but I'm working on a fix. I'm
> letting you know because I don't know if I'll need to make any changes in
> core (I suspect I will). Can you wait to release beta9 until I have a root
> cause?
