FAULT is not propagated over JMS binding in SwitchYard

Issue

• We have two SwitchYard applications (two switchyard.xml). Each of them has only one Camel XML route as implementation. They are connected via JMS binding, i.e.:

  [ ServiceA - RouteA - ReferenceA ] - JMS - [ ServiceB - RouteB - ReferenceB ]
  

• ReferenceB encounters a SOAPFault. This fault is properly progagated back to ServiceA (the Exchange state is always FAULT).

• However, when the message enters ReferenceA after being transferred over JMS, the fault switch is lost. The Exchange is in state OK, even though the message contains the SOAPFault.
