[JAVA] requestBody's with multiple options for content generate duplicate methods in Java classes

Description

Swagger-codegen is generating duplicate methods in a class when multiple request bodies are defined. This seems to only happen when the title and/or description is included in the scheme for the request body.

Copy the sample.yaml and config.json below and run the following command.

swagger-codegen generate -i sample.yaml -l java -c config.json

Once generated mnv package will generate the error above showing the duplicate methods in the class.

Suggest a fix/enhancement

Please fix this to allow title and description to be added to the schema of multiple request bodies.

Start with sample.yaml and config.json, then run swagger-codegen generate -i sample.yaml -l java -c config.json to reproduce the issue. Inspect the generated samples/src/main/java/com/sample/api/DefaultApi.java and verify that packaging no longer reports duplicate postData methods for the multiple request-body content options.
