OpenApi.json / yaml are not the same as one available during runtime

[ewoks]

Describe the bug
generated json|yaml file has different content than one available on host:8080/openapi

To Reproduce

1. execute: $ mvn io.openapitools.swagger:swagger-maven-plugin:2.1.4:generate
2. start application and send request like: curl <host>:8080/openapi > runtime_openapi.yaml
3. compare the files with diff <generated>-openapi.yaml runtime_openapi.yaml

Expected behavior
Both generated and runtime available openapi spec have the same content

@langecode maybe I misunderstood something? Your opinion would be very appreciated

Hi @ewoks

I think there could be a couple of things here. First of all your runtime generation and the build time generation may not run the same version of the Swagger library. I would think this may cause the difference.

Second I am not sure which of the two OpenAPI specifications you actually consider the most correct one? It seems the one have a "default" response where the other has "200". I am not quite sure what is the most correct - of course if you actually did document your responses using the Swagger OpenAPI annotations in the code that should be reflected in the generated documentation. However, if you have not actually documented anything I think it may be a bit more tricky.

Could you attach or link to both of the documents? Or would that reveal anything confidential...
