-----------------------------------------------------------------------
So we do have UTs for this resource under
*TestNamespacesInstanceResource.testNamespaceCreateAndDeletePBAndNoBody.*
Noticed the same already tests condition of _no body_ POST requests, and these
are always passing. Upon further investigation, I had found out this is due the
http request content-type. The passing tests are properly setting it to
"application/octet-stream". -Apparently, http clients such as curl default it
to "text/html", if not explicitly set-. In this case, jersey is then directing
the request to the wrong resource method, triggering the NPE.
