Exchange Context properties are not propagated across SwitchYard services using SCA reference binding

Issue

• I have a SwitchYard service (Service A) that uses a Camel XML implementation and SCA service/reference bindings.
• In this camel route, I use the <setProperty> tag to set a property on the Exchange. Also in this camel route, there is a <to> tag that invokes an external SwitchYard service (Service B), which is in a separate JAR file.

• Here is the definition of the camel route:

  <route>
      <from uri="switchyard://ServiceA"/>
      <setProperty propertyName="PROPERTY">
          <constant>Yes</constant>
      </setProperty>
      <to uri="switchyard://ServiceB"/>
  </route>
  

• According to the message tracer (org.switchyard.handlers.MessageTraceHandler), the last step of Service A before it goes to Service B, all the context properties look good. Then org.apache.camel.processor.FilterProcessor prints the exchange which is just a message body.

• Then the message tracer prints the first step in Service B. This printing has many of the context properties removed including the properties I set in the route, i.e. PROPERTY=Yes.
• How do I get some properties to propagate from Service A to Service B?
