Testing if a Player Chats not Working

So in the onEnable it does a timer for every 10 minutes. I set that lower to test it but The timer and broadcast goes through, but if I chat the words it tells me to it doesn't work. When the broadcast is played theres an error in console also.
TIMER:

Code:

    @SuppressWarnings("deprecation")
    @EventHandler
    public void timer(final AsyncPlayerChatEvent e)
    {
        this.getServer().getScheduler().scheduleAsyncRepeatingTask(this, new Runnable()
        {
            public void run()
            {
                for(Player player : Bukkit.getServer().getOnlinePlayers())
                {
                    double a = Math.random();
                    if(a < 0.1)
                    {
                    Bukkit.broadcastMessage("§8§l[§b§lUL§8§l] §f§lFirst one to type §e§lAlfjeAGbve%9359_V4*afh5A*tga §f§lwins a §0§lRandomCrate!");

Wow. That's quite a bit of thread safety violation you've got there. I'm not sure you know what you're doing.

How about you stop doing things on threads other than the main thread, especially things like this, which have a high chance of corrupting the server.

Also, it's a simple NullPointerException.

Looking at your code, the control flow really makes no sense at all, learn Java, and then read the Bukkit plugin tutorial.
