      1. add in standalone-teiid.xml the following resource adapter:

                      <resource-adapter id="swagger">

    Description

      When using the http://api.apis.guru/v2/specs/azure.com/redis/2017-10-01/ link as an endpoint for swagger resource adapter Teiid throws up the following error message (in bootstrapping phase), though with http://petstore.swagger.io/v2 endpoint according to the https://teiid.gitbooks.io/documents/reference/Swagger_Translator.html documentation the translator works:

      The http://api.apis.guru/v2/specs/azure.com/redis/2017-10-01/ endpoint supports swagger API according to the https://apis.guru/browse-apis/ link and I can see json output when requesting the http://api.apis.guru/v2/specs/azure.com/redis/2017-10-01/swagger.json link. Probably the NPE appears because of RefParameter type which is not handled in SwaggerMetadataProcessor.addProcedureParameters method which leads to name = null.
