Jerry Cwiklik commented on UIMA-1140:
-------------------------------------
Found another problem with dd2spring. Inner aggregate bean with remote delegate
is missing an OutputChannel Bean. This bean is required to send messages to a
remote delegate.

<!-- Async Aggregate: MeetingDetector_1.2 -->

> When an async aggregate is deployed, the request/reply queues for colocated
> delegates use an embedded broker. After UIMA-1130 is complete, all reply
> queues for remote delegates will be located on the same external broker
> hosting the delegate's request queue. At that point the function of the
> colocated broker can be replace with simple Java queues.
