Hi Chris,

thanks for bringing this up!
Can you create a „Backport Pull Request“ for jdk11u-dev [1] according to [2]?

Best regards,
Martin

Hi Boris and others,

Thanks for integrating this fix into jdk18 and jdk17.

This bug is also present in OpenJDK 11.0.10 and later (introduced by the
backport of JDK-8241234). I would suggest that this also be backported to
jdk11u. It applies cleanly. Let me know if there is any way for me to help
with this effort.

Thanks again for the support,
Chris Cole
