I've started getting with the last couple (5.5.4 and 5.5.5) versions of kotest.
[4.128s][warning][gc,alloc] ClassGraph-worker-16: Retried waiting for GCLocker too often allocating 1026 words

UnknownClass.Kotest > UnknownClass.initializationError FAILED
    org.junit.platform.commons.JUnitException at

UnknownClass.Kotest FAILED
If I keep re-running it eventually works. Is there a kotest leak? Or am I missing some kotest setting or is there something else I should be modifying? thx

I'm on a mac but it also happens on Github Actions (all using gradle)

Running out of memory scanning your classpath to find tests by the look of it - I can imagine that might be quite memory intensive, depending on how big it is.
