 Description   

I'm hitting a bunch of the following NPEs, after simply doing:

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.

https://git.opendaylight.org/gerrit/#/c/52979/ would turn the NPE instead into an IllegalStateException "No converter found for key: ..."

Comment by Michael Vorburger [ 09/Mar/17 ]

I've just tried to reproduce it, with a fresh Karaf rebuilt today (with mvn -U), and currently don't see it anymore... so either I did additional steps yesterday, or it's just been solved?! Closing for now, anyone seeing this again should re-open it.

Comment by Tomas Slusny [ 15/Mar/17 ]

It was fixed probably because Single Layer Serialization was set to on by default, so on OF1.3+ most of converters are not used anymore, including MatchConvertor.
