[1.10.2] ArrowNockEvent can't cancel

[SirWindfield 0]

I am fairly new to Minecraft Modding (I have around 5 years Java experience).
I want to prevent vanilla bows from firing. Looking into the docs for Forge I came across the ArrowNockEvent which should allow me to cancel any bow actions.
But even thought the event is marked as @Cancelable, Forge still throws an IllegalArgumentException when I try to cancel the event.
Here is the code if I am doing something wrong:

 

@SubscribeEvent(priority = EventPriority.HIGHEST)
    public void onHit(ArrowNockEvent event) {
        // not sure if machines can trigger this event
        if (event.getEntityPlayer() != null) {
            ItemStack bow = event.getBow();
            System.out.println(bow);
            System.out.println("Empty? " + ItemStackTools.isEmpty(bow));
            if (!ItemStackTools.isEmpty(bow)) {
                if(bow.getItem() instanceof ItemBow) {
                    event.setCanceled(true);
                }
            }
        }
    }

ArrowNockEvent is not @Cancelable: https://github.com/MinecraftForge/MinecraftForge/blob/1.11.x/src/main/java/net/minecraftforge/event/entity/player/ArrowNockEvent.java#L39

Looks like I had some older docs open. Is there any other practically disable vanilla bows without removing the recipe?

If you set the ActionResult in the event it will override the vanilla mechanics and result.
