Install a flow via RESTCONF with the following command

curl -v -X PUT -H "Content-Type: application/xml" -H "username: admin" -H "password: admin" -d @f1.xml http://127.0.0.1:8080/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/2/flow/124

When viewing the flow via RESTCONF

I see duplicated Match field and Instructions in the XML/JSON file.
