The test case included in your patch is failing for me with the following stack
trace. Any idea what may be happening?

> Possible infinite loop when WindowsNegotiateScheme authentication fails
> -----------------------------------------------------------------------
>
> Key: HTTPCLIENT-1545
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1545
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 4.4 Alpha1
> Environment: Windows
> Reporter: Ka-Lok Fung
> Fix For: 4.4 Alpha2
>
> Attachments: HTTPCLIENT-1545.patch.diff
>
>
> When {{WindowsNegotiateScheme}} authentication fails, it's possible for
> HttpClient to retry the authentication in an endless loop because the
> {{continueNeeded}} flag is not set to {{false}} when authentication fails.
> One possible way of causing authentication to fail is to use a service
> principle name that is outside your Windows domain (e.g., HTTP/EXAMPLE.COM).
