Oleg Kalnichevski resolved HTTPCLIENT-1616.
-------------------------------------------
Resolution: Invalid
I added an integration test to verify handling of NO_CONTENT response followed
by content body. HttpClient can handle cases like that just fine.

Without additional input from your side I have no other choice but to reject
the issue as invalid.

> Request 'hangs' on invalid response from server
> -----------------------------------------------
>
> Key: HTTPCLIENT-1616
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1616
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: Fluent HC, HttpClient
> Affects Versions: 4.3.6
> Environment: Java 8
> Running test with either Maven or IntelliJ.
> Reporter: Joost den Boer
>
> When using the fluent api to do a request and the response of the previous
> request was status NoContent, but (!) the server did send some content
> anyway, then the next request is blocked for a long time. No response is ever
> returned. Eventually some timeout will unblock the thread, but the request
> has failed.
> To reproduce this issue:
> - create a server which returns a NoContent with some text body.
> - do a first request
> - do a second request. This request hangs/blocks the thread for long time.
> We're using Fluent API to easily unit test our rest api. In a test class
> where a test was doing multiple requests, the first test would pass, but the
> second test would stall and eventually fail. Individually the tests were
> passing. I could not find any issue on the server side, so I tried another
> http client (Ning) which seemed to fix the issue. After rewriting the test to
> use Ning instead of HttpClient, the tests were successful, but when I changed
> it to reuse the same AsyncHttpClient, I got the same issue. However, because
> Ning does not block but throws an exception, I was finally able to find the
> issue which caused the problem: an endpoint returning a NoContent status, but
> with some text body.
> Even though this is a server issue, the httpclient should not block the
> thread for such a long time and also return a proper error so this kind of
> issues so the cause is easier to track down. Now, if I would not have used
> Ning, I would not have found the issue.
> The problem occurred when using Fluent Api, but I assume to cause for the
> thread to block and not return a proper error is in the HttpClient component.
