Приложение Keycloak vanilla не может быть настроено

Question

Основываясь на руководстве по keycloak, приложение Vanilla должно быть зарегистрировано в файле standalone.xml с сервера Keycloak. Ниже приведена упрощенная копия файла, включая подсистему приложения Vanilla.

<?xml version='1.0' encoding='UTF-8'?>

Вот ошибка, полученная при запуске сервера:

17:05:54,051 ERROR [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0055: Caught exception during boot: org.jboss.as.controller.persistence.ConfigurationPersistenceException: WFLYCTL0085: Failed to parse configuration

Caused by: javax.xml.stream.XMLStreamException: Unknown keycloak-server subsystem tag: secure-deployment

Кажется, что сервер не понимает, что означает тег подсистемы. Я использую keycloak-4.0.0.Beta1. Это проблема с keycloak 4.0?
