@DamonGuy @kumarabhi006 would be one of you kind enough to act as a sponsor for this change? I have an author status, but not a committer status.

Before issuing `/integate` I created a local test branch by merging master from 2-3 days ago into a copy of this branch. That merged cleanly. I reran the application level reproducer with the JDK image from that build and JDK-24. The problem on the application level was reproducible with JDK-24, but not anymore with this changeset in.

Thank you!
