      if File.exists?(js_file) || force == "json"
        # from_json returns object.class => json_class in the JSON.
        Chef::JSONCompat.from_json(IO.read(js_file))
      elsif File.exists?(rb_file) || force == "ruby"
        role = Chef::Role.new

      # Clients before 0.10 do not include env_run_lists, so only
      # merge if it's there.
      if o["env_run_lists"]
        env_run_list_hash.merge!(o["env_run_lists"])
