Willem Jiang commented on CAMEL-6404:
-------------------------------------
I just checked the code, the NPE is caused by the DefaultCxfBinding try to find
the processed object from CXF message. As the CXF_MESSAGE consume the input
stream and throw out the exception, the DefaultCxfBing get the NPE.
This issue can be fixed by letting DefaultCxfBinding ignore the CXF message
content when there is nothing. camel-cxf will take care of the fault message
(which is turned into an exception) then.
> cCXF route proxy cannot return Fault message to client when Dataformat is
> CXF_MESSAGE
