Bug: Not on FX application thread exception is inconsistent

My JavaFX program updates API objects in the background via a non FX
thread that, when changed by another program, are reflected in my JavaFX
GUI's controls by property binding, specifically TableView, Slider,
TextField, and ComboBox. Problem is, while JavaFX is OK with this for
TableView, Slider, and TextField, it throws a Not on FX application
thread exception *only* for the ComboBox.
The code for the slider looks like this:
private class ValueListener implements ChangeListener<Integer>
public void changed(ObservableValue<? extends Integer>
observable, Integer oldValue, Integer newValue)
(the slider variable is misleading, it's actually a VBox that contains a
Slider and a TextField. Need to change it but I digress.)
which works fine. However this:
private class ValueListener implements ChangeListener<E>
public void changed(ObservableValue<? extends E> observable, E
oldValue, E newValue)
doesn't for the ComboBox.
Is this a bug or is there some legitimate invisible reason as to why the
slider/textfield isn't throwing an error but the combobox one is?
