Hi Achim! I set out on that path this morning, but it looks like the camel-cxf feature in camel 2.15.2 has a dependency or a dependent feature with an upper bound which won't accept jetty 9:
Error executing command: Unable to resolve root: missing requirement [root] osgi.identity; osgi.identity=jetty; type=karaf.feature; version="[7.0.0,9.0.0)" I haven't had a chance to look/try a snapshot camel build, or figure out what exactly is imposing that requirement cxf, camel, and jetty features all installed fine, I got that error when installing camel-cxf feature.
