Java definition of Resource property with snake_case is generated to camelCase

Greetings,

I'm using the swagger-codegen maven plugin version 2.1.6.

I have a Resource object which needs some properties to be exposed as snake_case. This is required for the communication with an external third party API and cannot change.

In my yaml definition I have something like:

ResourceName:

  properties:

    snake_case_property:

      type: string

which creates a ResourceName class with the property camelCaseProperty and annotates it with JsonProperty("camelCaseProperty").

Is there any way to keep the snake_case? At least in the JsonProperty annotation.
