I've tested this by running the following reproducer that used to trigger this bug: `while true; do make -C ../build/fastdebug jdk test-only TEST=test/hotspot/jtreg/vmTestbase/nsk/jvmti/scenarios/allocation/AP01/ap01t001/TestDescription.java JTREG="JAVA_OPTIONS= -XX:+UseZGC -Xmx2g -XX:ZCollectionInterval=0.01"; done` ------------- PR: https://git.openjdk.java.net/jdk/pull/1204
