When building the openflowplugin/openflowplugin-parent
and then attempting to run the resulting controller in openflowplugin/distributions/base attempts to run mininet as described here:
https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin::End_to_End_Inventory
Do not work. They do work one commit back (on the current master on openflowplugin). I suspect we are hitting an MD-SAL bug.
The offending patch is here: https://git.opendaylight.org/gerrit/#/c/2887/
Its a very simple attempt to listen for all notifications and all data changes for purposes of debugging.
There suspected Exception thrown on the console is:

Note: here is the git log -3 for both openflowplugin and controller to assist in debugging:

DO NOT MERGE - For Debugging Purposes only
Added DebugProvider that outputs log messgae on on notifications
and DataChange events.
The only change is the addition of this bundle, and the
inventory nodes/node is no longer showing up in RESTCONF.
