anchor.diff:  the `/openapi` endpoint may be partitioned in the event that the MicroProfile
   runtime supports deployment of multiple applications. If an implementation wishes
   to support multiple applications within a MicroProfile runtime, the semantics of
  -the `/openapi` endpoint are expected to be the logical AND of all the applications
  +the `/openapi` endpoint are expected to be the logical union of all the applications
   in the runtime, which would imply merging multiple OpenAPI documents into a single
   valid document (handling conflicting IDs and unique names).
   
  
positive.code: ==== Location and formats
  
  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.
