Project: OpenEJB
Issue Type: Bug
Components: webservices
Affects Versions: 3.1.3
Environment: Windows, Tomcat with OpenEJB embedded

After upgrading OpenEJB from 3.1.2 (uses CXF 2.0.9) to OpenEJB 3.1.3 (uses CXF
2.2.10) CXF-based web-services are broken with the following exception on a
server side:

After debugging this with CXF 2.2.10 source we found that SAAJInInterceptor
called on each call (from WSS4JInInterceptor interceptor). Calling
SAAJInInterceptor by default is apparently new in CXF 2.2.10. When called
SAAJInInterceptor attempts to obtain
SOAPMessage doc = msg.getContent(SOAPMessage.class);
which is null in our case. This subsequently brings NullPointerException after
few steps.
