    Description

      The unit test org.apache.cassandra.repair.RepairJobTest#testNoTreesRetainedAfterDifference seems to be slightly flaky at least in 4.0. We haven't seen it failing on Butler, but after a failure on a patch branch, this repeated run shows a 0.28% flakiness:

      java.lang.reflect.InaccessibleObjectException: Unable to make field private jdk.internal.platform.cgroupv1.SubSystem$MemorySubSystem jdk.internal.platform.cgroupv1.Metrics.memory accessible: module java.base does not "opens jdk.internal.platform.cgroupv1" to unnamed module @157853da

      Flakiness is really low but the failure is clearly reproducible in j11.
