I think one problem may be in the serialization of the MessageExchange when
using the JMS / JCA flows. The exchange contains QName (for target service
and interface) and may also contain other QNames (soap headers are stored in
a map indexed by QNames).
We can easily change the first ones to use plain strings ({xxx}yy format),
but
it will be much more difficult for the ones we do not control.

Kit,
Apparently, you are using multiple (and different) versions of the QName
class. If this solution is running on multiple JVMs, ensure that
they're all of the same version. If it isn't, could you send us the
servicemix.xml file? Do you know which are the failing services, as
this might help us pinpoint the problem?
