Solved NullPointer at PlayerInteractEvent

Hi guys, I want to check, if the player does a rightclick with a slimeblock in air or on block and hold a golden apple in the left hand (so the new slot since 1.9) and eat them. The result was a nullpointerexception in the if e.getItem() line. Any ideas?

Code (Text):

public class RightClickListener implements Listener
{
    @EventHandler
     public void onClick(PlayerInteractEvent e)
    {
        if(e.getAction()== Action.RIGHT_CLICK_AIR|| Action.RIGHT_CLICK_BLOCK==e.getAction())
        {
            if(e.getItem().getType()==Material.SLIME_BLOCK)
            {
                e.setCancelled(true);
                e.getPlayer().addPotionEffect(new PotionEffect(PotionEffectType.JUMP,30*20,4));
                e.getPlayer().getInventory().setItem(e.getPlayer().getInventory().getHeldItemSlot(), new ItemStack(Material.AIR));
            }
          }
        }
}

 

Oh man,its to late for me ^^
