-------------------------------------
Regarding your question [@ user
forum|http://camel.465427.n5.nabble.com/camel-quickfix-RequestReplyExample-java-io-IOException-tp5723769p5728217.html]
the reason of the behavior you're observing is the following:
Removing {{MarketOrderStatusService}} from the route has the side effect of an
endless loop because each time the {{QuickfixjConsumer}} fires the out message
it triggers the {{QuickfixjEngine}} to dispatch this QuickFIX/J message (using
a new Camel Exchange object) down the hill to it's destination which is again
the *same* consumer. Then this consumers fires the same QuickFIX/J message out
again and so on and so on. One can also easily see this behaviour given the
stack trace when the whole loop ends up with a {{StackOverflowError}}:

That's why I will not take over your changes by {{QuickfixjConsumer}} given
through the second patch of yours.
> camel-quickfix: QuickfixjEndpoint should adhere the InOut exchange pattern if
