I have registered accelerator keys with the Scene (i.e. they are not associated with any control like a button or menu item). For KeyCodeCombination I am using cursor keys, e.g. new KeyCodeCombination(KeyCode.RIGHT). This is used to finely position selected elements in my UI. At first other controls with the focus appeared to be stealing they cursor key presses, e.g. obviously text fields would, so do tables and trees, but I eliminated that issue by requesting focus on my own node. I am certain that I had cursor keys working as accelerators in this case, but now they are not.

Ah.. I have just reproduce working cursor key accelerators with Java 8b106, but the same code fails with Java 8b108.
