Теперь работает в режиме отладки как true, приложение регистрируется как его запуск дважды. Я использую STS eclipse dev enviornment.

Класс приложения Spring Boot. 

@SpringBootApplication
public class App 
{
    private static final Logger logger = LogManager.getLogger(App.class);
    public static void main( String[] args)
    {
        logger.info("starting");
        SpringApplication.run(App.class, args);
        logger.info("Started");
    }
}

Это вызывает появление тем слушателя JMS дважды в моем обычном приложении, и затем я смог вернуться к зависимости log4j2 в примере загрузочного проекта. Если я удаляю зависимость log4j2, она запускается один раз. Не уверен, что здесь не так.

Спасибо за любую помощь.

Я думаю, вы должны установить для * false свойство additivity вашего регистратора.В противном случае будет установлено в значение по умолчанию и приведет к нескольким операторам журнала.

В коде это будет выглядеть следующим образом: 

logger.setadditivity(false);
