Hi, Thanks for the confirmation. I already added the two bundles to my custom distribution, so it works for me, but I wondered if the bundles were missed out by accident or on purpose, so I asked on this list before creating an issue in JIRA.

And this is fixed by KARAF-5897[1]. For now, as a workaround, you can download [2] and copy it to $KARAF_HOME/lib/boot folder then it should work. Sorry for any inconvenience.
