Hm, your concern regarding Centos-6 is valid, since jsvc in Centos6 is not usable.
But every other distro has a good and running jsvc and I see absolutly no point in replacing a running and maintained package.
As a compromise, let me fix jsvc in Bigtop 1.1 and push this particular ticket to 1.2 . My proposal was to remove centos6 in 1.2 and check whether your concerns are valid.
Amir presented a fix a possible solution a few weeks ago, let me put this fix in in a different JIRA for 1.1 in order to move forward.
