Why does my exception gets wrapped within a AggregateMessageDeliveryException?

[davidcyp]

Hello,

I have a @ServiceActivator which throws an exception, e.g. throw new FooException( "Invalid foo", e );

I have following configuration:

  <integration:exception-type-router input-channel="errorChannel" default-output-channel="globalExceptionChannel">
    <integration:mapping exception-type="org.acme.exception.FooException"
                         channel="fooExceptionChannel"/>
  </integration:exception-type-router>

However, my message is always routed to the globalExceptionChannel and my FooException is wrapped within an AggregateMessageDeliveryException. Where does this happen? Why does this happen? And how can I route my exception to the fooExceptionChannel?

Any help appreciated!
