--------------------------------------
Hi Ryan,
You can see the java.lang.IllegalStateException: component is not owner
for many reasons, it MAY come from your incorrect workflow.
As the code your point out here, we do need done(exchange) (which will set DONE
status for message exchange) even for InOnly MEP.
So the code here is correct IMHO.
Regards
Freeman

> This happens if there is no out message on the exchange when it's an InOut,
> after processing the retrycontinuation. It seems as though this if statement:
> NormalizedMessage outMsg = exchange.getMessage("out");
> if (outMsg != null) {
> sendOut(exchange, outMsg, request, response);
> }
> done(exchange);
> should throw an exception if there is no out message and the Exchange is an
> InOut message. Otherwise, the done message is called at an inappropriate
> time since the sendOut gets skipped and the done then gets called.
