Импорт sun.security.pkcs11 не может быть разрешен. ⇐ JAVA

[Anonymous]

Я пытаюсь написать код для цифровой подписи PDF-документа с использованием аппаратного токена (epass2003auto) с использованием библиотеки itext7, взяв примеры из самой документации. Но я продолжаю получать ошибку «Невозможно разрешить импорт sun.security.pkcs11». Я использую проект eclipse Maven для запуска приложения. Может ли кто-нибудь помочь мне в этом?
Вот мой код:
