[CONTROLLER-1242] calling RESTCONF RPC requires Content-Type header - not added in apidocs on Firefox if input is null?

I'm running the ncmount app from coretutorials.

in using the APIDOCs I found that I could issue ncmount:list-nodes from Safari but got error 500 from Firefox.

Using Postman to manually issue the RPC works ok:

{
"output":

{ "nc-oper-nodes": [ "xrvr-d", "xrvr-c", "xrvr-b", "controller-config", "xrvr-a" ], "nc-config-nodes": [ "controller-config", "xrvr-c", "xrvr-d", "xrvr-a", "xrvr-b" ] }

}

but if I remove the headers (Accept: application/json and Content-Type application/json) from my Postman request it fails:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<title>Error 500 Server Error</title>
</head>
<body>

seems that the issue is the lack of a Content-Type: header (even though there's no content per-se as this is an RPC with no input parms)

so I then tried an RPC that took a parameter (ncmount:show-node).

that worked fine from both firefox and safari in apidocs.
