This project is great, glad I found it. Noticed this running against my own project:

The Java OpenAPI Tools code generator templates for go support type: object and Any Type ({} in OpenApi syntax) types, which I believe should just translate to map[string]interface{} and interface{} respectively, I think.

object just errors out in the current oapi-codegen, and using {} results in an empty anonymous struct type, which isn't quite right.
