Looks like something in `ByModulatorOptimizationStrategyTest` is failing. It
appears something in that test is using `sample().by().by()` and needs to be
corrected or removed. That's probably an issue with the outdated test and not
any issue with your change itself.
VOTE +1 pending test fix.
> Prevent sample step from having multiple by modulators

> Key: TINKERPOP-3150
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3150
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.7.3
> Reporter: Andrea C
> Priority: Minor
>
> Sample step will ignore previous by modulators if multiple are specified,
> which can be misleading to the user. Instead, similar to
> https://issues.apache.org/jira/browse/TINKERPOP-3121 multiple by modulators
> should be prevented with sample.
