[jira] [Updated] (CXF-6408) HTTP Conduit throws NPE exception for "invalid" 401 HTTP response

    Description: 
Hi guys,

In process of using RESTful client based on Apache CXF JAX-RS with activated auto-redirect option, I observed NPE on my logs. The short investigation shows that the problem was caused by Web Service side, that send "401 Unauthorized" HTTP response without "WWW-Authenticate" header.

In this case, on HTTPConduit class when we try to handle retransmits (by auto-redirect option), we expect that response message MUST contains authentication params, but header map doesn't contain it. As a result we observe the following exception:

I understand  that described case is invalid by server, but I think it will be cool if we log some more informative. For example: "Authentication parameters is not specified".

Thank you!
