How to get response body if server send status 400/500

Question

I need to implement a web service client for a third-party web service. Unfortunately the web service operator decided to send a HTTP status code 400 if a "normal" fault occurred. That means if something is going wrong the web service sends something like this in the body

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <soapenv:Fault>
         <faultcode>ERROR</faultcode>
         <faultstring>[M0002] The following dealer information was not accepted. [C07AB02157XX]</faultstring>
      </soapenv:Fault>
   </soapenv:Body>
</soapenv:Envelope>

and sets the HTTP-StatusCode to 400 and Content-Type to 'text/xml'. This results in a WebServiceException in my code which does not contain the Fault itself. In such case my stacktrace looks like this:

Now I can not figure out how to get access to the original body with the Fault itself.

I played a bit and adding my own OutInterceptors with Phase.SEND

class MyOutInterceptor extends AbstractPhaseInterceptor<Message> {
    public MyOutInterceptor() {
        super(Phase.SEND);
    }

    @Override
    public void handleFault(Message message) {
        // ...
    }

    @Override
    public void handleMessage(Message message) throws Fault {
        // ...
    }
}

In such a case the handleFault method is fired, but I can't figure out how to access the response body as message.getContent(InputStream.class) returns null.

It seems that Apache CXF - handle response with HTTP 400 code is exactly my problem. Unfortunately this question was not solved.

I've just found a solution for this problem after digging more about this in the net. I've found this request in apache jira https://issues.apache.org/jira/browse/CXF-4241 This solved my problem!
