Daniel Kulp commented on CXF-8950:
----------------------------------
Discussing this with [~reta], we don't believe this is a valid bug. You are
specifically closing the client (in the try with resources block) but then
continuing to use objects (the Response) that are expecting the client to still
be open/connected. You need to be fully done with the client prior to
calling close (or don't call close and allow the garbage collector to clean it
up, but that would not be deterministic as to when that would happen). Or
re-use the clients (which would have other benefits with keep-alives, http/2,
etc..).
When closing the client, all resources associated with that client are no
longer valid. You would definitely need to fully consume the entity prior to
closing the client.

> Key: CXF-8950
> URL: https://issues.apache.org/jira/browse/CXF-8950
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 4.0.3, 4.0.4
> Reporter: Sebastian Violet
> Assignee: Daniel Kulp
> Priority: Critical
> Fix For: 3.6.3, 4.0.4
>
> Attachments: CXF-HTTPClient-LargePayload.zip
>
>
> When processing requests using the JAX RS client which used the new
> HttpClient, there is the input stream is closed prematurely.
>
> [^CXF-HTTPClient-LargePayload.zip] , you will see that we are using
> {*}Response{*}, because we are interested in getting response status as well
> as the response headers. This fails with the following error:
