     * This method internally creates a {@link RevocationRequestHandler} instance
     * and calls its {@link RevocationRequestHandler#handle(MultivaluedMap, String)
     * handle()} method with the {@code parameters} argument and the {@code authorization}
     * argument. Then, this method uses the value returned from the {@code handle()}
     * method as a response from this method.
     * 
     *
     * 
     * When {@code RevocationRequestHandler.handle()} method raises a {@link
     * WebApplicationException}, this method calls {@link #onError(WebApplicationException)
     * onError()} method with the exception. The default implementation of {@code onError()}
     * does nothing. You
     * can override the method as necessary. After calling {@code onError()} method,
     * this method calls {@code getResponse()} method of the exception and uses the
     * returned value as a response from this method.
     * 
     *
     * @param api
     *         An implementation of {@link AuthleteApi}.
     *
     * @param parameters
     *         Request parameters of a revocation request.
     *
     * @param authorization
     *         The value of {@code Authorization} header.
     *
     * @return
     *         A response that should be returned to the client application.
