   Vendors are required to fetch a single document named `openapi` with an extension
  -of `yml`, `yaml` or `json`, inside the application's `META-INF` folder.  If there
  -is more than one document found that matches one of these extensions the behavior
  -of which file is chosen is undefined (i.e. each vendor may implement their own logic),
  -which means that application developers should only place a single `openapi` document
  -into that folder.
