> // peerClusterId value, which is the same as the source clusterId
> if (clusterId.equals(peerClusterId) &&
> !replicationEndpoint.canReplicateToSameCluster()) {
> this.terminate("ClusterId " + clusterId + " is replicating to itself:
> peerClusterId "
> + peerClusterId + " which is not allowed by ReplicationEndpoint:"
> + replicationEndpoint.getClass().getName(), null, false);
> this.manager.removeSource(this);
> return;
