Maybe there is some misinterpretation about the ticket description, but I'd expect `class GenCollectedHeap` to be removed completely with this ticket.

Could you enable GHA (https://wiki.openjdk.org/display/SKARA/Testing) to catch potential issues for all platforms? It should show sth like "19 successful checks", e.g. in https://github.com/openjdk/jdk/pull/16560.
