Thanks for your help Claus. I am now using a single onException clause with a workaround which is setting the source endpoint type in the header so that I can take different actions (processors) according to the message origin. Its working fine for now and I find out that I need to handle some specific exceptions differently I'll use doTry but for a much smaller scope.
