Description
We are seeing an NPE within org.apache.servicemix.cxfbc.interceptors.StaxJbiWrapper, which marshals our message to the bus, during unmrashaling by servicemix-cxf-se.
The message content of our message is document based, but sub elements of message parameters are not ns-qualified (I believe this to be the problem). This service implementation worked fine on servicemix 3 with prior releases of servicemix-cxf-bc, and we are in the process of porting to servicemix 4 with OSGi bundles.
Here is the stacktrace for the code in question (this was grabbed by my debugger, but not propagated to the servicemix.log unfortunately):

The issue I see is that this method, "getPrefix()", is receiving a null back from parts.get(part).get(reader).getNamespaceURI(), which it turns around an tries to get the length on. I stepped into the code here and found this to be the case. Should be an easy fix.
I created a workaround in my interceptor chain by fooling the servicemix-cxf-bc JbiInWsdl1Interceptor into creating a DOMSource instead of a StaxJbiWrapper, by temporarily setting the message state to "client" instead of "server" mode....ugly but it works. This only works because the StaxJbiWrapper will throw UnsupportedOperationException back to the caller in this case.
The NPE is being translated to an IOException as you can see below:
