There may be a backport, you'll want to follow that issue upstream

[jjscl8888]

When is this problem expected to be solved? @karianna

[karianna]

You'll need to track https://bugs.openjdk.org/browse/JDK-8331735 for progress.

[CH3CHO]

You'll need to track https://bugs.openjdk.org/browse/JDK-8331735 for progress.

However, Java 21 isn't in the affected versions list. That's why we wondered whether the fix would be backported to 21 or not. Would you add 21 into the list as well?

[karianna]

Added 21
