Веб-запуск Java не работает в автономном режиме (NoRouteToHostException / UnknownHostException)

Я хочу настроить свое приложение для веб-запуска / jnlp так, чтобы при отсутствии подключения к Интернету оно запускалось из кеша. Тем не менее, когда я отключаюсь от Интернета, я всегда получаю исключение NoRouteToHostException или UnknownHostException, несмотря на конфигурацию ниже.

Думаю, я правильно настроил разрешенные офлайн и обновил теги / атрибуты; Я не могу найти причину, по которой веб-старт все еще пытается найти хост. У меня определенно есть приложение, кэшированное с моего предыдущего запуска, когда я был подключен.
