Исключение Spring Integration всегда не достигает errorChannel

<bean id = "triggerFileScanner" class = "abc.xyz">

Иногда исключения из активатора службы отправляются в канал ошибок, но иногда не отправляются.

У меня есть канал ошибки, определенный ниже:

<int:channel id = "errorChannel" />

<bean id = "exceptionHandler" class=my.custom.ExceptionHandler">
</bean>
<int:service-activator id = "errorLogger" input-channel = "errorChannel" method = "handle" ref = "exceptionHandler">
</int:service-activator>

У меня этот канал ошибки используется во многих интеграциях, и в моих активаторах служб я просто выполняю исключение throw («Сообщение»)
