[1.8] Crash on World#getEntitiesWithinAABB

I'm trying to make an item that affects entities within a radius around the player using World#getEntitiesWithinAABB and AxisAlignedBB#expand, but the game crashes whenever I try to create the List<EntityLiving> of entities to affect.

 

Here's the crash log:

And the method in question:

public void onArmorTick(World world, EntityPlayer player, ItemStack itemStack)
{
	if(KeyBindings.ability.isPressed())
	{
		if(!world.getEntitiesWithinAABB(EntityLiving.class, player.getBoundingBox().expand(10, 10, 10)).isEmpty()) // the problematic line
		{
			List<EntityLiving> entities = world.getEntitiesWithinAABB(EntityLiving.class, player.getBoundingBox().expand(10, 10, 10));
			for(EntityLiving entity : entities)
			{
				if(!entity.equals(player))
				{
					entity.addPotionEffect(new PotionEffect(2, 2000, 99));
				}
			}
		}
	}
}
