Comments
Fix request: Request fix approval for jdk12u and jdk11u. This test-only fix needs to go together with JDK-8221083. Risk is low. Patch applies cleanly after JDK-8221083.

Add next to run only with Serial GC: * @requires vm.gc.Serial or if you want to run in tier1 which uses default G1: * @requires vm.gc.Serial | vm.gc.G1 | vm.gc == "null" and add flag: -XX:-UseG1GC
