> 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.
