Ruud de Jong commented on CXF-6144:
-----------------------------------

It sounds indeed awful lot like that.
Let me test 2.7.12...

> WS-Security fails if body has signature on WSS4JInInterceptor

> If a WebService has WS-Security with the soap body as part of the signature, 
> the incoming security check (by the WSS4JInInterceptor) will break.
> This bugs was introduced in 2.7.9 and is still present in the current 
> codebase (3.0.3).
> This problem is caused by the WSS4JInInterceptor. It uses the 
> "SAAJInInterceptor.INSTANCE.handleMessage(msg)" on getSOAPMessage to convert 
> a CXF SoapMessage to a javax.xml.soap.SOAPMessage.
> During this conversion, the SAAJInInterceptor add an empty text-node at the 
> end of the soap-body.
> This breaks when the soap-body is part of the signature.
> The old 2.7.8 version of the SAAJInInterceptor did (line 223:) 
> StaxUtils.readDocElements(soapMessage.getSOAPPart().getEnvelope().getBody(), 
> xmlReader, true, true);
> The new 2.7.9 version does (line 140:)
> StaxUtils.copy(xmlReader1, new SAAJStreamWriter(e.getSOAPPart(), 
> e.getSOAPPart().getEnvelope().getBody()), true, true);
> If I use XmlDebug in WSS4JInInterceptor right after this call, the old 
> version returns:
> (see attachment soap-body-2.7.8.txt)
> while the new version returns:
> (see attachment soap-body-2.7.9.txt)
> Notice the additional #text/"\n" inside the body.
> For this debug logging, I changed the WSS4JInInterceptor:
> {noformat}
>     private SOAPMessage getSOAPMessage(SoapMessage msg) {
>         SAAJInInterceptor.INSTANCE.handleMessage(msg);
>         return msg.getContent(SOAPMessage.class);
>     }
> {noformat}
> to 
> {noformat}
>       private SOAPMessage getSOAPMessage(SoapMessage msg) {
>               SAAJInInterceptor.INSTANCE.handleMessage(msg);
>               SOAPMessage soapMsg = msg.getContent(SOAPMessage.class);
>               SOAPPart soapPart = soapMsg.getSOAPPart();
>               debugDomDocument(soapPart);
>               return soapMsg;
>       }
>       private void debugDomDocument(Document doc) {
>               ByteArrayOutputStream baos = new ByteArrayOutputStream();
>               PrintStream ps = new PrintStream(baos);
>               XmlDebug.printDocument(ps, doc);
>               ps.flush();
>               ps.close();
>               LOG.warn("SoapPart via XmlDebug: " + baos.toString());
>       }
> {noformat}
