With lighty 16.0.0, ODL yang tools 8.03, netconf 3.0.2,.. (Phosphorus SR2) when a device is attached containing the BBF yang mode "bbf-software-management@2021-09-17.yang", there are yang tool errors and ODL will not connect to the device.

Attached is an error log as well as a tar file of a miminum set of yang to reproduce the issue using a NETCONF testtool simulator.

To reproduce, use a NETCONF testtool simulator pointing to the yang files as the schema directory from the attached bbf-sw-mgr-yang.tar.gz file. Add the device to ODL.

The API used for example was:
PUT http://controller:8181/restconf/data/network-topology:network-topology/topology=topology-netconf/node=justSwMgr
