Can you summarize your proposed changes below as It was a bit unclear to me what you meant. I can create a separate PR with those changes later. ------------- PR Comment: https://git.openjdk.org/jdk/pull/24829#issuecomment-2847309534 PR Comment: https://git.openjdk.org/jdk/pull/24829#issuecomment-2847314767
