> VisibleValidator gets chained multiple times, while each one working on the same NodeState will run the exact same check, NodeStateUtils.isHidden(name). One execution should be enough.
> Below stacktrace has 9 instances chained. Code for propertyAdded as in the stacktrace below in 1.4 is [here|https://github.com/apache/jackrabbit-oak/blob/1.4/oak-core/src/main/java/org/apache/jackrabbit/oak/spi/commit/VisibleValidator.java#L82-L83]. 
> Also found a similar stacktrace in OAK-6358 with 12 instances.
> This might be a small optimization to make, especially if there are many properties added, and if there is apparently another variable factor in how many instances there are.
> According to [~stillalex]:
> This is directly related to the hierarchy level (so if a change is 5 levels deep, you'll see 5 validators chained there) and the short fix is to fix calls [creating new VisibleValidators|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-store-spi/src/main/java/org/apache/jackrabbit/oak/spi/commit/VisibleValidator.java#L44] to unwrap if needed, like [here|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-store-spi/src/main/java/org/apache/jackrabbit/oak/spi/commit/VisibleEditor.java#L38].
