How to generate Map<UUID, Integer> instead of Map<String, Integer>

Hi atumius ,

It looks like the format isn't applied to the inhertience (in Java at least).

Could you create  a ticket on https://github.com/swagger-api/swagger-codegen/issues/new with the details of how you're using codegen (via the web, via cli, via maven, etc), what language/framework and anything else that might help recreate the issue - so that the devs can take a look at it.

Hope that helps!
