IndexOutOfBoundsException when clicking on a MenuItem in Java FX (JDK 1.7.25)

This bug was found by adding a MenuBar to a Toolbar and reducing the width of the stage so that the toolbar puts the menu bar in "side dropdown menu". When the MenuItem was clicked, this results in IndexOutOfBoundsException.
