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

[Padma Priya Kowlwar]

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

I am receiving this error after upgrading camel from 2.X to 3.0. Any
inputs to solve this issue will be appreciated.


Thanks,
