----------------------------------------
I forgot a file during the KARAF-4863 commit, hence the NPE.

> After same debugging, I found out that because of KARAR-4863 the file "jmx.acl.cfg" no longer gets added to the bundle "org.apache.karaf.instance.core-4.1.0-SNAPSHOT.jar" resulting in a NullPointerException.
> I am not sure, but I think the entry "etc/jmx.acl.cfg" must be removed from the "resources" array defined in "org.apache.karaf.instance.core.internal.InstanceServiceImpl". Can someone please check if there a more resource declarations that must be removed from the array to get "instance:create" working.
