[solved] Why does this produce a null pointer exception?

Basically, I want gold boots to negate fall damage. The following does it, sort of ...

Code:

        if (event.getCause().toString() == "FALL") {
            if (event.getEntity() instanceof Player) {
                player = (Player) event.getEntity();
                if(player.getInventory().getBoots().getType() != null) {
                    if (player.getInventory().getBoots().getTypeId() == 317) {
                        event.setCancelled(true);
                        event.getEntity().getLocation().getWorld().playEffect(event.getEntity().getLocation(), Effect.EXTINGUISH, 1);
                    }
                }
            }
        }

Code:

Change this:

Code:

 if(player.getInventory().getBoots().getType() != null) {

to:

Code:

 if(player.getInventory().getBoots() != null) {

Thank you!
