Restconf breaks [Transaction Factory was closed...]

Checked out master branch of Lithium in the integration project, built the project, and ran karaf. Installed the following features:

odl-base-all
odl-restconf-all
odl-netconf-connector-all
odl-yangtools-all
odl-netconf-all
odl-netconf-mdsal
odl-config-persister-all

I added a netconf connector via the REST API, (and failed to do any netconf operations with an error about the yang-ext mountpoint not existing), so I restarted the controller. I tried to do a GET operation on :8181/restconf/operational/opendaylight-inventory:nodes and got this exception as a result.
