Comments
It might be David. Aleksey requested to backport JDK-8317581, and this issue needs to be backported first for a clean backport of JDK-8317581. Then I also saw that for other architecture enablement was done in JDK-21.

Note fast-locking is only an experimental feature in 21.

Fix Request This backport is required because It seems community is planning to enable this feature in JDK-21 and on s390x we have merged/enabled it on JDK-22.
