Richard, I haven't quite got my head round what you're doing but I did notice that you were chaining attributeWhenReady calls https://github.com/rdowner/brooklyn-consul/blob/master/catalog/consul/consul-server-cluster.bom#L50 which I don't think you can do as attributeWhenReady returns a BrooklynDSLDeferredSupplier.
