    Description

      In Boron, get-schema RPC call is not working any more and new solution has to be implemented.

      The server returns a 500 error saying there is a java type casting issue.

      Reproduce:

      1. Grab the latest distribution code and compile it, do a fresh install
      2. Install the necessary features in karaf:
      feature:install odl-netconf-connector-ssh odl-mdsal-apidocs
      3. Do a GET on the get-schema RPC at
      /restconf/operations/opendaylight-inventory:nodes/node/controller-config/yang-ext:mount/ietf-netconf-monitoring:get-schema

      You will see the following error:
