Before taking this out of Draft, change the title to make it a Backport-style PR as recommended by Skara in the Description. The title should be "Backport COMMITHASH" where "COMMITHASH" is the 40-char commit hash of the bug you are backporting.

Having said that, I believe that this PR should be redone against the jdk25u-dev repo. @GoeLin, who is the maintainer of jdk25u, can direct you.
