Hi Claus, I apologise for not giving useful information in my previous email. I've resolved my issue - it was PEBKAC, the message was failing to return because what I was returning was not serializable. I'd forgotten that inner classes (in this case, a comparator) retained references to their owning classes - so my 'serializable' tree-set was also trying to serialize the containing service. As the Camel book says, it's the #1 rule of camel proxies. :/
Thank you for your quick response though.
