If I understand correctly, the situation is that you are sending many requests, all with credentials encoded in the headers. Occasionally a 401 response is received that does not have the WWW-Authenticate header.
This would need for the request to have failed authentication (when many requests with same credentials had passed) and for the resulting 401 response to have been incorrectly generated by jetty. It seems very unlikely that the one request that has a problem with auth, also tickles some issue to make a bad challenge. More likely something unrelated to authentication is emitting a spurious 401 response? Can you capture the full headers of the bad 401?
