If I understood you correctly, you want to know from where this Exchange
which holds the exception, have you tried something like
`exchange.getFromEndpoint` or `exchange.getFromRouteId`? Which as I
understood should gives from which endpoint this exchange has been
originated from. However, I think `Exchange.FAILURE_ENDPOINT` will contain
the information about the last time Camel has sent the exchange to, hence I
think you would see this information after a `to` route. However I am not
100% sure though.
