@prrace Do I understand correctly that _“`createPrivateValue` is no longer used”_ means `MultiUIDefaults` is never used with `ProxyLazyValue`?

The [`MultiUIDefaults` class](https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/javax/swing/MultiUIDefaults.java) is used in `UIManager`:
