Petals ESB Container

Do not remove In, Out or Fault from an Exchange before sending it

    Before sending an exchange, the router "cleans" its messages to remove those that were already here before, for example if it's a DONE or ERROR status, all message are removed, or if it's an OUT, the IN message is removed.
    There is more strange and not always coherent logic to it.

    We shouldn't do that, I guess the objective is to save bandwidth when transferring over the network, but removing these messages kind of breaks the JBI specs, and makes checking the for state error very difficult (as in PETALSESBCONT-74).

    The alternative is to simply have more "intelligent" transporters (for now only the NIO transporter) so that it only transfers what should be transferred.

Note: this can't be done for send (async) because it is not the same object used between sending as a consumer and receiving as a consumer: if we remove, for example, the IN message when sending as a provider, then how can the container from the consumer side can know from which object to restore from the IN message?
Or it should store it on the side but then how can it know how long it should keep it?

Or we should do that "optimisation" from within the CDK when using sendAsync and not the container… because sendAsync knows how long the consumer is waiting for its answer!
