Wow, thanks for the quick reply.

Thanks for the hint with the contributions, I have updated my email addresses to include the one I used in the commit.

I did not create separate ticket, but the closest ticket is this one: https://github.com/swagger-api/swagger-codegen/issues/3950 (discussion about different template engines)

The pull request allows to use the handlebars template engine by additionally setting the system property "'Dhandlebars", e.g.

java -Dmodels -Dhandlebars -cp swagger-codegen-cli.jar io.swagger.codegen.SwaggerCodegen generate
-l java
-t handlebarsTemplateLocation

If the "-Dhandlebars" system property is not present, everything will be rendered with the Mustache engine.

Thanks and best regards, Tobias
