ClassCastException when accessing augmentations

Using Port configuration for Peer Group under XML config file at the first run of KARAF will end on Cast Exception, when receiving onDataTreeChanged notification.

On the other side if the configuration is used once karaf is already running, no cast exception will be trowed.

Line causing the exception is the getAugmantation

 
if (config != null) {
    final NeighborTransportConfig peerTc = config.getAugmentation(NeighborTransportConfig.class);   <----Line 156
    ....
    ....
