Change looks good, I just feel we shouldn't be catering to `null` here at all.

modules/javafx.controls/src/main/java/javafx/scene/control/TableView.java line 2645:

To get `rows` to be `null` you'd have to call this method as: `selectIndices(2, null)` -- IMHO that should result in an exception, and not be accepted to be the same as `selectIndices(2)` or `selectIndices(2, new int[0])`.

I checked the documentation, and it does not mention that `null` is allowed here, which means it isn't.

Also: weird method signature, but I guess if you want to enforce at least one parameter it could be done this way.
