Apache Camel returns NullPointerException when calling CXF Endpoint. This is failing after upgrading camel from 2.X to 3.0 - camel-cxf

Question

I have a CXFEndpoint as below
CxfEndpoint cxfEndpoint =new CxfEndpoint();
cxfEndpoint.setAddress("http://localhost:9201/mock");
cxfEndpoint.setDataFormat(DataFormat.CXF_MESSAGE);
cxfEndpoint.setWsdlURL(serviceSoapOutboundWsdl);
cxfEndpoint.setContinuationTimeout(continutionTimeout);
cxfEndpoint.getOutFaultInterceptors().add(postOutFaultInterceptor);
.....
.....
exchange.setProperty("cxfEndpoint", cxfEndpoint);
I call this endpoint from my route builder as below
.toD("${exchangeProperty.cxfEndpoint}")
I am getting following exception
Exception occured while sending outbound message to Receiver::: org.apache.camel.FailedToCreateProducerException: Failed to create Producer for endpoint: http://localhost:9201/mock. Reason: java.lang.NullPointerException
