2.7.2->3.0.0milestone1 update yields No DestinationFactory upon ws-publish?

I am upgrading my cxf/sts/wss4j dependencies, and am running into the
following error when publishing a web-service in the initialization of my
CXFNonSpringServlet. This code worked fine on the 2.7.2 code-base, but is
throwing the following exception on the 3.0.0-milestone1 versions.

org.apache.cxf.BusException: No DestinationFactory was found for the
namespace http://schemas.xmlsoap.org/soap/http.

org.apache.cxf.bus.managers.DestinationFactoryManagerImpl.getDestinationFactory(DestinationFactoryManagerImpl.java:122)
org.apache.cxf.endpoint.ServerImpl.initDestination(ServerImpl.java:88)
org.apache.cxf.endpoint.ServerImpl.<init>(ServerImpl.java:72)

org.apache.cxf.frontend.ServerFactoryBean.create(ServerFactoryBean.java:160)

org.apache.cxf.jaxws.JaxWsServerFactoryBean.create(JaxWsServerFactoryBean.java:211)
org.forgerock.openam.sts.STSBroker.loadBus(STSBroker.java:45)

Here is the code which generates the error:
public class STSBroker extends CXFNonSpringServlet {
@Override
public void loadBus(ServletConfig servletConfig) {
super.loadBus(servletConfig);
Bus bus = getBus();
BusFactory.setDefaultBus(bus);
JaxWsServerFactoryBean serverFactoryBean = new
JaxWsServerFactoryBean();
serverFactoryBean.setAddress("/sts_publish/");
serverFactoryBean.setServiceBean(new STSPublishImpl());
serverFactoryBean.create(); //this is line 45 in the stack-trace
above

The listing of updated dependencies follow. No code changes were made other
than the import statement changes required by the migration from
org.apache.ws.security to org.apache.wss4j in the STS (and these seem
unrelated to the error). I confirmed the presence of cxf-rt-transports-http
and cxf-rt-transports-http-jetty .jar files in WEB-INF/lib of my .war file,
as that seemed to be a culprit in previous manifestations of the soap “No
DestinationFactory was found” error.

Maven version changes:
cxf-rt-frontend-jaxws: 2.7.2->3.0.0-milestone1
cxf-rt-transports-http:2.7.2->3.0.0-milestone1
cxf-rt-core:2.7.2->2.7.8
cxf-rt-bindings-soap:2.7.2->3.0.0-milestone1
cxf-api:2.7.2->2.7.8
cxf-rt-transports-http-jetty:2.7.2->3.0.0-milestone1
cxf-rt-ws-security:2.7.2->3.0.0-milestone1
cxf-rt-ws-policy:2.7.2->3.0.0-milestone1
cxf-services-sts-core:2.7.2->3.0.0-milestone1
wss4j(org.apache.ws.security):1.6.9->1.6.13
xmlsec(org.apache.santuario):1.5.3->1.5.6

Any ideas?

Thanks
