What does this mean???

[Aphomer]

This isn't a general question. But since I'm not able to open up topics in the appropriate forum for it, i'll have to post it here. I've got a minecraft Bukkit server that I just opened up this month, my friends and I have added about 30 plugins to it so far and when I logged on today, the following message popped up in the console. What does all of this mean and what do I need to do about it?
