The DSW loads the intent map via Spring from an XML file. For this import it needs access to some namespace handlers that are provided by the CXF bundle. If the Spring OSGi Extender bundles are not completely started before the DSW tries to load the map, the loading fails as the namespace handlers are not found.
A possible solution would be to change the startup of the DSW from the OSGi activator to Spring. This way the DSW would be started by the Spring OSGi Extender bundles once they are ready and the DSW could successfully load the map.
