Integration tests fail relatively rarely when running on Karaf 3 and more often when running on Karaf 4 with message similar to this:

MappingServiceIntegrationTest.testMultiSite:418->testMultiSiteScenarioA:762 SMR contained Eid [_address=Ipv4PrefixBinary [_ipv4AddressBinary=Ipv4AddressBinary [_value=[-64, 0, 1, 1]], _ipv4MaskLength=32, augmentation=[]], _addressType=class org.opendaylight.yang.gen.v1.urn.opendaylight.lfm.lisp.binary.address.types.rev160504.Ipv4PrefixBinaryAfi, _virtualNetworkId=InstanceIdType [_value=2], augmentation=[]] which wasn't expected.

This points to a concurrency issue in the SMR handling code, which may lead to incorrect SMRs being sent and xTRs maintaining state that is out of date, potentially blackholing traffic.

See https://logs.opendaylight.org/releng/jenkins092/lispflowmapping-merge-carbon/119/console.log.gz for an example.
