>> This patch adds another retry condition for rest requests. When a rest call uses authentication but fails with 401 "unauthorized", we need to give it at least one more try. The authentication mechanism for JBS works with time limited tokens that sometimes need to be renewed. This can only be detected through failing with 401. On the retry, the dynamic authorization provider (authGen.getAuthHeaders()) will get to run again and will detect the stale token.
