NotifyTask throws IllegalArgumentException upon FlowStatistics

During OF testing with ODL from https://jenkins.opendaylight.org/integration/view/Integration%20jobs/job/integration-master-project-centralized-integration/1945/
operational state does not reflect changes.
This probably affects also https://jenkins.opendaylight.org/integration/view/Integration%20jobs/job/integration-master-csit-sp-of13/416/

As for direct symptoms to blame, there is this exception:
