The test task's JVM args for this run are:

-Duse.JTREG_TEST_THREAD_FACTORY=Virtual -XX:+UseZGC -XX:+ZGenerational -XX:-VerifyContinuations

This failure first showed up in jdk-23+13-925-tier5 which only contains the fix for:

JDK-8326586 Improve Speed of System.map

so I've tagged this bug as a regression.
