Some java error in the console?

Hello there, this is Kevin here again. Last time, I posted on some server lag issues and I think I got some issues fixed but anyways, let's move on to my topic.

So anyways, during the current days while there is a server lag, there seems to be a same constant java error messages that keeps over-flowing my console. Back before my server even lag, this java error code never spammed my console. But now, it's been popping up recently and it has been annoying me and I been dying to know how to get rid of it.

Here's the error message:

Now I know since I read this over and over again but I later realized that this has to do with players doing a quit options on my server. Any way of how to fix it?

 

You could try the latest version of Console. It is for 1.4.7 but it might not have the same errors.

 

19:01:00 [SEVERE] Could not pass event PlayerQuitEvent to Console v1.0
org.bukkit.event.EventException

There is an error with the plugin Console;
at me.barwnikk.console.console.onSer(console.java:714)

Talk to the developer about it and see if it can be fixed.
