Hi Joye,

Here you go, in the gremlin console with janusgraph-0.6.3:

```
gremlin> graph = JanusGraphFactory.open('conf/janusgraph-inmemory.properties')
==>standardjanusgraph[inmemory:[127.0.0.1]]
gremlin> g = graph.traversal()
==>graphtraversalsource[standardjanusgraph[inmemory:[127.0.0.1]], standard]
gremlin> g.addV('v1')
==>v[4112]
gremlin> g.V().order().by("name")
08:00:35 WARN  org.janusgraph.graphdb.transaction.StandardJanusGraphTx - Query requires iterating over all vertices [()]. For better performance, use indexes
==>v[4112]
```
