No, I'm just simply using the deliverychannel to send out, which is
mentioned in the servicemix docs as something that you can do. I assume
that means it's recommended :) I did see that I can inject a
ComponentContext and so I'm currently changing my outbound messages to that
to see if I can get around this problem. I think I just can't use the
DeliveryContext in the same Pojo (same thread).
