Wrong response format

[weierophinney]

Hi,

OAuth2 specification describe in point 5.2. response format for invalid request.
But in AuthController::tokenAction if status code is beetwen 400 and 500, we return reposne in problem+json format, not in format from specification. Why?

I know that client can recognize content-type of response, but many OAuth2 clients recognize format from specification.
