> I'm implementing a web service using CXF. After upgrading the CXF endpoint from SOAP 1.1 to SOAP 1.2, error handling no longer works properly. Instead of receiving SOAP faults from the web service, I receive an empty document, which breaks my client software. A stack trace is logged on the web server. The stack trace includes the following:
> java.lang.NullPointerException
>   at org.apache.cxf.staxutils.W3CDOMStreamWriter.writeNamespace(W3CDOMStreamWriter.java:209)
>   at org.apache.cxf.staxutils.StaxUtils.getUniquePrefix(StaxUtils.java:1287)
>   at org.apache.cxf.binding.soap.interceptor.Soap12FaultOutInterceptor$Soap12FaultOutInterceptorInternal.handleMessage(Soap12FaultOutInterceptor.java:77)
>   at org.apache.cxf.binding.soap.interceptor.Soap12FaultOutInterceptor$Soap12FaultOutInterceptorInternal.handleMessage(Soap12FaultOutInterceptor.java:55)   
> It looks like Soap11FaultOutInterceptor has some code to handle a special case where writer.getPrefix() returns null, and that this code wasn't copied over to Soap12FaultOutInterceptor.
