[OPNFLWPLUG-1] NPE in during Handshake for OF 1.0

Mon, 27 Sep 2021 09:00:59 +0000

Using the mininet from here:

https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin::End_to_End_Inventory

And running:

mininet@mininet-vm:~$ sudo mn --topo single,3 --controller 'remote,ip=192.168.195.1:6653' --switch ovsk,protocols=OpenFlow10

(to use OF 1.0).

Against the controller built in openflowplugin/distribution/base

I get the following NPE at the OSGI console:
