nullpointer

[ˈyøøniks]

Czemu to wyrzuca nulla?

        final Location prev = player.getLocation().clone();
        new BukkitRunnable() {
            long run;
            Vector v;
            Location now;
            
			@SuppressWarnings("deprecation")
			public void run() {
                if ((player.isOnGround() && this.run > 0L) || player.isDead() || !player.isOnline() || this.now.getY() < 0.0) {
                    this.cancel();
                    return;
                }

A dokladniej to:

                if ((player.isOnGround() && this.run > 0L) || player.isDead() || !player.isOnline() || this.now.getY() < 0.0) {

error:
