Bug is currently not reproduceable on 2.16 or 2.17. It has been fixed, so this should not be a blocker for the new version. However, determining the exact change will require further investigation to backport to 2.15.

*Edit: bug appears to be flaky and intermittent in nature on all versions, will require further investigation
