Tests not passing: TestStatsReporter Flush not flushing

[TbirdDuncan]

Expected Behavior

I'd expect running ./gradlew test or build would pass on a clean main branch. That is not happening.
WorkflowFailedMetricsTests.java runs a @before setup that contains: reporter.flush()
Some methods are experiencing failures when ran in conjunction with other tests, such as:

Steps to Reproduce the Problem

1. Run ./gradlew build, or ./gradlew test

Sounds like this test might be flaky - we'll take a look
