Description

wfarner reported a build failure re: newly added coverage:

* What went wrong:
Execution failed for task ':jacocoTestReport'.
> Thanks for adding the first test coverage to: org/apache/aurora/scheduler/async/OfferQueue$OfferQueueImpl$2 please remove it from the legacyClassesWithoutCoverage list. Expression: (coverage == 0). Values: coverage = 6

However running the build locally neither I nor zmanji were able to reproduce. Here's the sha I'm running from:

    Kill code to serve ApiBeta help pages that's no longer used now that the content is served directly.

    Blacklist org/apache/aurora/scheduler/http/api/ApiBeta$2 which has no coverage.
