Take this quickstart: the git://github.com/fabric8-quickstarts/jboss-fuse-camel-log.git
and try adding to the pom.xml:
<feature>shell</feature>
<feature>management</feature>
<feature>scr</feature>
It will build fine but result in a Karaf container which does not have have scr:* commands or SCR management MBeans enabled.
