I've created a temporary branch for the upgrade to OSGi Core r7 (well, felix framework 6.0, currently under vote). I think this should be targeted for Karaf 4.3, but it's still missing an update for equinox. Anyway, I didn't want to drop the branch I used to test the felix release so I've uploaded it there: https://github.com/apache/karaf/tree/osgi-r7
