Is the goal for reproducible builds? Backporting this change alone isn't enough. The following are needed:

https://bugs.openjdk.org/issues/?jql=labels%20%3D%20reproducible-build%20AND%20labels%20%3D%20cds%20ORDER%20BY%20fixVersion%20ASC

However, the CDS code has changed significantly since JDK 17, so backporting will be very difficult.

Please follow https://wiki.openjdk.org/display/JDKUpdates/How+to+contribute+or+backport+a+fix and have a discussion on the [jdk-updates-dev mailing list](https://mail.openjdk.org/mailman/listinfo/jdk-updates-dev) before proceeding.
