Hi,
I had a look at the improvements to test ValidateISO4217.java that are not in 21 and spoiled the clean
backport. See also
https://github.com/openjdk/jdk/commits/master/test/jdk/java/util/Currency/ValidateISO4217.java
In detail these are
    [8354344: Test behavior after cut-over for future ISO 4217 currency](https://github.com/openjdk/jdk/commit/1526dd81d9b5bf4abaac1546c370cf7a056d01dc)
[8354343: Hardening of Currency tests for not yet defined future ISO 4217 currency](https://github.com/openjdk/jdk/commit/ac41bc31c96951b9fe51c22d16f31bdc1806a881)

The ISO 4217 Update is a recurring change, and thus having clean backports and more testing would be nice.
But the changes are not straight forward to backport, so I think we should better accept the recurring need for reviews and not backport them.

The resolve for this change is trivial after all.
