WSO2 ESB sample 440 fails (JSON/XML proxy) - wso2

Question

wso2esb-4.0.3
I am able to execute other samples. I do have ESB and StockService running. Looks like the JSON transformation is happening, but that the jsonclient can't handle a JSON response.
ant jsonclient -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/services/JSONProxy
yields
[java] org.apache.axis2.AxisFault: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character '{' (code 123) in prolog; expected '<'

I'm not an Axis2 client expert. Anyone have a work around to get this example working?
Sending a curl with a JSON payload from the example also yields errors:
curl -X POST -H 'Content-type: application/json' -d '{"getQuote":{"request":{"symbol":"IBM"}}}' http://localhost:8280/services/JSONProxy

When you are converting the message from json to soap11, make sure you set the endpoint format to soap11. You can do it by setting the endpoint address like this: <address uri="http://localhost:9000/services/SimpleStockQuoteService" format="soap11"/> in the synapse configuration.
