The OpenJDK contribution guide has details on how to propose changes to the JDK https://openjdk.org/guide/. For a change like this, that doesn't have a corresponding JBS issue already filed, the suggestion is to first ask in a relevant mailing list whether the change is worth doing. Can you create a discussion in the concurrency-dev mailing list https://mail.openjdk.org/mailman/listinfo/concurrency-discuss and explain what this change is about? The mailing list requires subscription, so please subscribe before posting. That mailing list link has details on how to subscribe.
