Backport the fix of JDK-8180450 to JDK 11?

[林子熠(层风)]

JDK-8180450(https://bugs.openjdk.org/browse/JDK-8180450) has a mojor performance impact on concurrent  Java applications. Thanks to Andrew Haley to get it fixed in OpenJDK 23.
However, some applications suffered from the issue have to stay in the older OpenJDK version. For example, Spark requires OpenJDK11, but suffers the secondary supertype cache problem as well(https://github.com/scala/bug/issues/9823). 
Is there a plan to backported the fix to JDK 11 in the future?

Thank you!
