./nuxeo-distribution/nuxeo-distribution-resources/src/main/resources/jetty-base/config/jetty.xml is calling:
<Call class="org.nuxeo.runtime.jtajca.NuxeoContainer" name="install"/>
but the method install of org.nuxeo.runtime.jtajca.NuxeoContainer is now protected.
default-repository-config.xml and ds-config.xml need to be migrated.
