Solved PlayerRespawnEvent will not fire.

I cant figure out why, but my playerRespawnEvent always returns a NPE. Always on the same line, even if i add and remove code, so the line its pointing to is not the error. I have even deleted all my code leaving just a message in the event, and i still get an NPE. This is my code right now:

Code:

@EventHandler (priority = EventPriority.HIGHEST)
    public void onrespawn(PlayerRespawnEvent e){ 
        Bukkit.broadcastMessage("respawn event");
}

and heres the stacktrace:

Code:
