A pr is created https://github.com/openjdk/jdk/pull/21736 so we might not need to do the exclusion. Just to confirm that the PR will be backported to jdk23

Will double check before next release.

I'll backport it to jdk23 once I get approval for PR on head stream. Also for s390x-specific issues, feel free to tag/mail me :-)
