Affects Version/s: 1.6.1
Fix Version/s: None
RawXMLInOutMessageReceiver can be only used in JSON services now .
However, JSON/badgerfish builder can be improved by handling RPCMessageReceiver correctly. I can't attach the patch because i have copy pasted and created my own formatters and builders(please find the source attached):
1) It is possible to solve the namespace problem described at  by explicitly converting JSON/badgerfish to SOAP in JSONbadgerfish builder :
public OMElement processDocument(InputStream inputStream, String contentType,
MessageContext messageContext) throws AxisFault
2) jettison 1.2 has cool feature called setIgnoreNamespaces which allows to use json formatter with any xml.
We use the these builders and formatters successfully with JSON/badgerfish request and JSON response.
