 * If not specified then a container will assume that any type can be produced.
 * Method level annotations override a class level annotation. A container
 * is responsible for ensuring that the method invoked is capable of producing
 * one of the media types requested in the HTTP request. If no such method is
 * available the container must respond with a HTTP "406 Not Acceptable" as
 * specified by RFC 2616.
 *
 * A method for which there is a single-valued {@code @Produces}
 * is not required to set the media type of representations that it produces:
 * the container will use the value of the {@code @Produces} when
 * sending a response.
