Comments
Fix Request (14u) This is a followup for JDK-8242054 backport. Patch applies cleanly to 14u, passes hotspot_gc_shenandoah, tier{1,2} with Shenandoah enabled. Patch is completely isolated in Shenandoah code.

The test is only available since jdk11 (JDK-8205694), dropping 8-shenandoah from affects-field.
