> 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 header params, but map doesn't contain it. As a result we observe the following exception:

> I understand that described case is invalid by server side, but I think it will be really cool if we write to log some more informative message.
> For example: "Authentication parameters is not specified by server. URI: <TEST_SERVER>".
> Thank you!
