Start by running the documented swagger-codegen-cli command with the supplied OpenAPI YAML and inspect the generated jaxrs-jersey model files. Trace the model-generation templates or entry points used by the jaxrs-jersey library, then verify that the schema and property XML metadata produce the expected XML annotations.
