Duplicate messages in the console

[Blayung]

I'm not sure if this is an issue with canyon, but both my plugin, other plugins and the server can log a single message up to 10 times for no known reason.

(The one below is my plugin, there's a Runnable scheduled to run every 5 seconds, and it uses System.out.println to print run and Bukkit.broadcast to print test)

These are just random parts of my server log. What's going on there?
