JDK 8u compatible patch for TestGCBasher in openjdk-11 sources
Apply this patch to JDK 11 sources of gcbasher in test/hotspot/jtreg/gc/stress/gcbasher of jdk-updates/jdk11u, revision e321dd1f202a (tag jdk-11.0.4+3). Then compile basher sources with JDK 8u and you should be able to run the JDK 8 reproducer.
Root cause of this problem is JDK-8225716 OpenJDK version 8u222-b07 (an EA tag) or better will have the root cause fixed.
