Unstable tests on master

[StephenFlavin]

Describe the bug

mvn install was failing on SimplePublisherTest#stochastic_onNext_multiProducerSeemsThreadSafe and ProfileFileSupplierTest#aggregate_duplicateOptionsGivenReloadingProfileFirst_preservesPrecedence there may be more.

I came across this while doing the PR checklist.

Expected Behavior

the master branch has repeatable tests that don't fail

Current Behavior

a couple of flakey test preventing builds, the flakeyness might be the result of a wider issue

Reproduction Steps

Run SimplePublisherTest#stochastic_onNext_multiProducerSeemsThreadSafe on repeat

Possible Solution

No response

Are they flaky or they fail every time?
Can you post the logs with the error?

[StephenFlavin]

flaky sorry if I was unclear.

[debora-ito]

@StephenFlavin Thank you for the logs. We'll change them to make less flaky.
