Yes can do.
> ExecutionGraphMetricsTest fails on Windows CI
> ---------------------------------------------

> Key: FLINK-6567
> URL: https://issues.apache.org/jira/browse/FLINK-6567
> Project: Flink
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.3.0, 1.4.0
> Reporter: Chesnay Schepler
> Assignee: Till Rohrmann
> Priority: Blocker
> Labels: test-stability
> Fix For: 1.6.0
>
>
> The {{testExecutionGraphRestartTimeMetric}} fails every time i run it on
> AppVeyor. It also very rarely failed for me locally.
> The test fails at Line 235 if the RUNNING timestamp is equal to the
> RESTARTING timestamp, which may happen when combining a fast test with a low
> resolution clock.
> A simple fix would be to increase the timestamp between RUNNING and
> RESTARTING by adding a 50ms sleep timeout into the
> {{TestingRestartStrategy#canRestart()}} method, as this one is called before
> transitioning to the RESTARTING state.
