NPE when running IOFiber

See original GitHub issue

I am occasionally seeing an error with cats-effect 3.2.9 that I can’t yet reproduce locally. The following is the full stacktrace:

java.lang.NullPointerException: null
    at cats.effect.internals.Utils.setThreadTokenAndRefCount(Utils.java:57)
    at cats.effect.IOFiber.run(IOFiber.scala)
    at cats.effect.unsafe.WorkerThread.run(WorkerThread.scala:435)

I’m not sure where cats.effect.internals.Utils.setThreadTokenAndRefCount comes from, or what’s setting this off. Will continue make some attempts to minimise, but in the meantime the stacktrace makes it look like there’s some error in the heart of cats-effect. If there’s anything anyone can think of trying to help me produce a more useful report, please let me know - I am currently mystified by pretty much every aspect of the error

I don’t think so, thanks very much though. I’ll raise an issue against new relic.
