This started failing a lot about 2 weeks ago.
In the Nightly tests, we run a matrix of plans with various Java and Scala versions so that same tests are run a lot. This test is almost bound to fail in at least one run now.

@He-Pin https://github.com/apache/pekko/pull/2769 improved one test in MetricsBasedResizerSpec but a different test in that class is flaky too. "record the performance log with the correct pool size"
Is it worth making a similar change for that test?

The `MetricsBasedResizerSpec` flakiness has been addressed on `main` by several commits:
- \`2769\` (merged) — chore: fix flaky test in MetricsBasedResizerSpec
- \`b0f9779b4\` — test: fix flaky "stop an underutilizationStreak when fully utilized" on JDK 25 (#2898)
- \`ebddbc211\` — test: stabilize two flaky tests on JDK21+/virtualized nightly (#2949)
Suggest closing as fixed — please reopen if it recurs on latest `main`.

I found this gist that allows you to rerun each test multiple times. Even with bug numbers, the MetricsBasedResizerSpec tests are always pass for me locally. Maybe it is something about other tests, possibly run in parallel, that is affecting this test case.

Failures are happening in 1.1 nightly tests so it seems like maybe this is just an issue with these tests as opposed to some new commit that has made them flaky.

This suite has been flaky even in Akka days.
https://github.com/search?q=repo%3Aakka%2Fakka+MetricsBasedResizerSpec&type=issues
Not sure why it has become flakier recently. It fails for us with Pekko 1.0 and there are no recent changes there (much more regularly recently than a few months ago).
