TestIndexFileDeleter.testExcInDecRef test failure [LUCENE-9839]
It isn't reproducible for me (at least trying again a single time). I'm guessing a concurrency issue?

This same error appeared in my PR's auto check as well: https://github.com/apache/lucene/runs/3873024350?check_suite_focus=true
And went away after retry...
This random failure is still happening in recent CI builds (e.g. here), but never seems to repro for me.
I'll try to add some "verbosity on failure" to the test.
I'm wondering if, in CI with multiplier, this test hits something like file handle limit (too many open files) or similar, and masks the exc somehow?
I just popped this when pushing an unrelated commit. I see @mikemccand added more verbosity, but then reverted the verbosity (maybe because it caused the test to never fail anymore?)

I wonder if "concurrency issue" is jumping to conclusions. My machine has almost no concurrency: 1 cpu with 2 cores...
I too have seen this time to time. It does replicate rarely on my machine if I run it many times (thousands) with stress-ng eating my CPU cores.
Do we want to add back some verbosity on failure? There is something weird going on here :/
