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

[carlisom]

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.
