Suggest a fix/enhancement

Add support for security attribute / authorizations

Start by locating the JAX-RS server templates that generate the @ApiOperation annotation and trace how the declaration's security scopes are represented. Done means generated Java methods include the authorization or scope information from the OpenAPI security data; verify this with a representative generated server output.
