ignoreUnknownJacksonAnnotation configuration property is simply getting ignored

[bansalm2001]

Hello! Trying to add @JsonIgnoreProperties(ignoreUnknown = true) annotation to all the generated model classes. Trying to accomplish by adding the configuration property: ignoreUnknownJacksonAnnotation But it seems that it simply gets ignored. I have generated swagger-codegen-cli.jar from the master branch. It appears that this should be an out of box solution.

Please help!
