private RedstoneControl plugin = new RedstoneControl();

It's because your creating a new instance of your main class. Bukkit instantiates your class for you and only one instance can exist so it throws this exception. This also means that you cannot create a subclass of your main class so it should be final.

Yes, what Skionz said.

So how would I fix this? I could combine the classes?

Don't instantiate your main class and pass the instance that Bukkit creates through your other classes constructors.

Thanks, that helped!
