The CXF-DOSGi distributed discovery demo doesn't work.

This demo is described here: http://cxf.apache.org/dosgi-discovery-demo-page.html

It seems that the client and the server bundles individually do work. The server bundle does register a remote endpoint and the client bundle does seem to look up the service, but something seems to go wrong with the interaction with the zookeeper server.
I did try to configure it both through standalone.xml and load/org.apache.cxf.dosgi.diovery.zookeeper.cfg file.

standalone.xml content:

        <subsystem xmlns="urn:jboss:domain:osgi:1.0" activation="lazy">
            <configuration pid="org.apache.cxf.dosgi.discovery.zookeeper">
                <property name="zookeeper.host">
                    127.0.0.1
                </property>
            </configuration>
