Я запустил издателя в пабе Google, используя кодировку [1]. После окончания работы издателя я закрыл издателя как [2]. Но при запуске я получаю сообщение об ошибке [3] о том, что издательне правильно выключен.Я использую версию 1.61.0 pubsub.Есть ли способ справиться с этой ошибкой?

Make sure to call shutdown()/shutdownNow() and wait until awaitTermination() returns true.
