Description

Happens when the Async Routing Engine variant of the Loop logic kicks in, and there are more than two processors in the loop body, e.g.

.loop(3)
  .to("activemq:queue:abc?exchangePattern=InOut")
  .to("activemq:queue:def?exchangePattern=InOut")
.end()

The wrong inflight Exchange is copied (instead of the original one), and since the implicit Pipeline has copied the OUT message from the 1st endpoint to the IN message, the original IN message is lost fully.
