I wonder though, whether should we upstream our changes to those listeners (refactoring) to synchronize with JDK and not have to deal with conflicts all the time. However we would still run into trouble during backports, as we would like to have CRaC changes synchronized across JDK majors (or not, if we don't expect further development in the Attach Listeners?)

Agree that it's better to upstream our changes. I'll follow up on it. I hope that upstreaming work shouldn't block the merge.
