Starting karaf on OSX Maverics with the following features integration project stable/helium build of 24 Nov 2014 results in a catastrophic run-away icorrect TCP socket creation/closure for for IPv6 connections. The suspect is netconf. The jvm runs out of file-handles and crashes.

feature:install odl-netconf-connector-all odl-restconf-noauth odl-toaster-ui

Error (although unclear if this is an effect or the root issue)
