Bukkit

I created a plugin that works (almost); and I'm trying to integrate your API.

On server start I get this message:

[ControllableMobsAPI]  is not used by any plugins.

and when I execute this instruction:

final ControllableMob<?> controllableEntity = ControllableMobs.putUnderControl(_explorer);

(_explorer is a LivingEntity)

I get this error

[00:01:10 INFO]: [ControllableMobsAPI] initialized by an unknown component
