This was found while investigating NETCONF-800: when requesting a non-existent stream using:
curl -u admin:admin http://127.0.0.1:8181/rests/data/ietf-restconf-monitoring:restconf-state/streams/stream/data-change-event-subscription/opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE
we end up with a HTTP status 500. This boils down to a IAE being thrown and not wrapped:
