Может кто-нибудь сказать, пожалуйста, как запустить Log4j2-Kafka-Appender в среде OSGi?Консольные и файловые приложения работают нормально.Но когда я добавляю Kafka-Appender, как описано в документации, я получаю следующую ошибку:

Я обнаружил следующую ошибку в Log4j2 Bugtracker, которая, похоже, является этой ошибкой, но я не знаю, какреализовать предложенное решение в среде OSGi.
