ColouredConsoleSender cannot be cast?

Hi,

My problem is strange for me.

I dont understand this error when i try execute command from console

Code:java

Caused by: java.lang.ClassCastException: org.bukkit.craftbukkit.command.ColouredConsoleSender cannot be cast to org.bukkit.entity.Player

Someone can say me how to repair it ?

Line Plugin.java:80:
Player player = (Player)sender;

This is full error:

Code:java

You don't know if the sender is actually a player yet. Check if the sender is an instance of a Player, otherwise send some message to the sender or execute some alternate code. For example, a way to check this:

Code:java

if(sender instanceof Player)
