Looks good. I ran the tests and they pass. Left a few optional comments.
Maybe @kevinrushforth will want to have a look too before you merge.

If you like this style, you could do
`parent.getChildren().forEach(Node::updateDisabled);`. I find these more
readable, but it's up to you.

Not sure if these comments are intended to be used for something. I doubt it
though.

Since you changed the copyright year on the other files, you might want to do
this one too. There is a script that will do it anyway, so it doesn't matter.

I suggest to continue this test with a `g.setDisable(false)` to check both
directions. The first group of assertions test the initial state, not a change
to `false`.
Same for the other test.
