Charset of @Produces Annotation are ignored in Accept header

[carstenlaengerer]

REST WS with charset in the Produce annotations result in wrong swagger.json. The charset is simple ignored.

@produces("text/plain;charset=UTF-8") results to "produces" : [ "text/plain" ] in the swagger.json.

Hence, Calling the the REST WS by swagger result in HTTP 406

Should be checked with consumes as well.
