Description

This shows in the context of WebHCat and Hive (which recently moved to httpcomponents:httpclient:4.4) but could happen in other places.

URLEncodedUtils.parse(String, Charset) which is called from PseudoAuthenticationHandler.getUserName() with the 1st argument produced by HttpServletRequest.getQueryString().
The later returns NULL if there is no query string in the URL.

in httpcoponents:httpclient:4.2.5 parse() gracefully handles first argument being NULL, but in 4.4 it NPEs.
