> HTTP Verb OPTIONS requires to have Accept header defined
> {code}
> $ curl -X OPTIONS http://127.0.0.1:10090/metrics/vendor
> No exporter found for method OPTIONS and media type
> {code}
> I have to specify json mediatype
> {code}
> curl -X OPTIONS -H "Accept: application/json" http://127.0.0.1:10090/metrics/vendor
> {code}
> I was expecting that I get -the json response or at least more- helpful message.
> OpenLiberty returns 
> {code}
> Error 406: CWMMC0000I: The accept header format */* is incorrect.
> {code}
> which at least points user to define proper header
> Update:
> Spec requires header to be defined, so WF could be a bit more helpful in the response message
> {code}
> The implementation must return a 406 response code if the request’s HTTP Accept header 
> for an OPTIONS request does not match application/json.
