Infinity loop or something ?

Code:java

@EventHandler(priority = EventPriority.NORMAL, ignoreCancelled = false)
    public void onPlayerToggleSprintEvent(PlayerToggleSprintEvent event)
    {
        Player player = event.getPlayer();
        while (player.isSprinting() == true)
        {
            if (player.hasPotionEffect(PotionEffectType.SPEED) == false)
            {
                player.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 10000, 10));
                if (player.hasPotionEffect(PotionEffectType.SPEED) == false)
                {
                    player.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 10000, 10));
                }
            };
        }
        player.removePotionEffect(PotionEffectType.SPEED);
        player.removePotionEffect(PotionEffectType.JUMP);
    }

after I sprint 1 time my server will not responding.
Please help me I'm really newbie.

 

Why not just use if() instead of while(), and then have an else() that would remove the effects? The way you have it, the while()'s statement will never be false.
