Actually this does work as advertised. I Had previously made a mistake. I have to build the project from the root.

   mvn clean install


Does it. I would like to know why I get MULTIPLE notifications when mininet connects.

Does it. I would like to know why I get MULTIPLE notifications when mininet connects.

To get rid of the MULTIPLE notifications issue :

     final InstanceIdentifier<Table> instanceIdentifier = InstanceIdentifier.builder(Nodes.class).child(Node.class)
.augmentation(FlowCapableNode.class).child(Table.class).build();

//final DataTreeIdentifier<Table> dataTreeIdentifier = new DataTreeIdentifier(LogicalDatastoreType.OPERATIONAL,
//  instanceIdentifier);
final DataTreeIdentifier<FlowCapableNode> dataTreeIdentifier = new DataTreeIdentifier(LogicalDatastoreType.OPERATIONAL, getWildcardPath());

this.dataTreeChangeListenerRegistration = this.dataBroker.registerDataTreeChangeListener(dataTreeIdentifier,
wakeupListener);
