So the 24u backport didn't happen until Jan 31, so I guess the 21u backport was based on 25 and this was missed.

Opened [JDK-8352097](https://bugs.openjdk.org/browse/JDK-8352097) to track this for the upcoming releases and I'll also propose backporting the `zone.tab` removal ([JDK-8166983](https://bugs.openjdk.org/browse/JDK-8166983)) for the July releases.
