The only one I see is the manual application in `ValidateISO4217.java` of the new currency code because of the different indentation. This is due to 8u not having the refactoring in [JDK-8310923](https://bugs.openjdk.org/browse/JDK-8310923) which would in turn require a new JTreg and the headaches that involves (it took a long time to go to 11u , IIRC). Were there any others?
