[Not sure which project to file this in; perhaps rather genius than controller?]

Like OPNFLWPLUG-866 (probably totally unrelated),

I'm hitting a bunch of the following exceptions, after simply doing,
as of f6bda1bdfd01a44948fe154883140538c2558151:

cd netvirt/vpnservice/distribution/karaf
mvn clean package

cd target/assembly/bin
./karaf

opendaylight-user@root>feature:install odl-netvirt-openstack

I've also hit http://localhost:8181/controller/nb/v2/neutron/ in a Browser (which 404s), and I'm not sure that's what causes the NPEs or the mere start up.
