Компонент с именем "XXX" уже определен в этом модуле в JBoss 7.1.1

Я не создал имя spring bean с TimerServiceDispatcher в своем приложении. Но исключение JBoss throw из-за TimerServiceDispatcher уже определено в этом модуле. Я не знаю, в чем проблема. Что мне не хватает? Что мне нужно сделать?

Мое приложение использует Seam 2.3, spring 3.0 и JPA 2.0. Я не использую EJB.
