Propagate SOAPFault with simple Camel proxy - web-services

Question

I'm trying to create a simple WS proxy using Switchyard 1.1 with Camel:
--> PromotedService --> Camel --> ProxifiedService
With the current configuration I'm able to send and recieve messages without any problem.
However, when the ProxifiedService throws a SoapFault it is not propagated to the caller of the PromotedService.
What can I do to ensure the the PromotedServiceCaller receives the SOAPFault as reponse?
This is what I have tried so far:
onException(Exception.class)
.process(
new Processor() {
public void process(Exchange exchange) throws Exception {
SoapFault fault = exchange.getProperty(Exchange.EXCEPTION_CAUGHT, SoapFault.class);
System.out.println("Fault: " + fault); // --> This returns NULL
Exception excep = exchange.getProperty(Exchange.EXCEPTION_CAUGHT, Exception.class);
System.out.println("excep: " + excep);
System.out.println("excep message: " + excep.getMessage());
System.out.println("excep cause: " + excep.getCause());
SoapFault SOAP_FAULT = new SoapFault(excep.getMessage(), SoapFault.FAULT_CODE_CLIENT);
Element detail = SOAP_FAULT.getOrCreateDetail();
Document doc = detail.getOwnerDocument();
Text tn = doc.createTextNode("this is a test");
detail.appendChild(tn);
exchange.getOut().setFault(true);
exchange.getOut().setBody(SOAP_FAULT);
exchange.setProperty(Exchange.ERRORHANDLER_HANDLED, false);
exchange.removeProperty("CamelExceptionCaught");
}
})
.handled(true)
.end();
from("switchyard://PromotedService")
.process(myProc) // --> I just add some headers here to the original request.
.handleFault()
.to("switchyard://ProxifiedService").end();
This is the SOAPFault generated by the ProxifiedService:
<soapenv:Envelope xmlns:ser="http://service.admin.ws.my.company/" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
</soapenv:Header>
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring>Missing valid token.</faultstring>
</soapenv:Fault>
</soapenv:Body>
And this the message the caller is really receiving:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header/>
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>org.switchyard.HandlerException: org.apache.cxf.binding.soap.SoapFault: javax.xml.transform.dom.DOMSource#663dcb96</faultstring>
</soap:Fault>
</soap:Body>
</soap:Envelope>
Thank you!

onException() only takes Throwable. In your code the argument is SoapFault which is not Throwable.
This will work
onException(SOAPException.class)
