Github user dkuppitz commented on the issue:
https://github.com/apache/tinkerpop/pull/711
Which scenario would end up throwing this exception? Tried this:
```
gremlin> g = TinkerFactory.createModern().traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g.V().repeat().times(2)
java.lang.NullPointerException
```
... but it's obviously still a NPE thrown in [line
67](https://github.com/apache/tinkerpop/blob/53db262511e9d84b1262522fc841ded825df4fc6/gremlin-core/src/main/java/org/apache/tinkerpop/gremlin/process/traversal/step/branch/RepeatStep.java#L67).
