Не могу понять, почему _arr2==null?
Объясните, пожалуйста.

var sg:Singleton = Singleton._instance;
trace(sg.arr1);
trace(sg.arr2);

public class Singleton
{
	public static const ARR1:Array = [1, 2, 3];
	public static const _instance = new Singleton();
	public static const ARR2:Array = [3, 2, 1];
 
	private var _arr1:Array = ARR1;
	private var _arr2:Array = ARR2;
 
	public function Singleton()
	{
		if (_instance)
			throw new Error("Class is singleton.");
	}
 
	public function get arr1():Array { return _arr1; }		
	public function get arr2():Array { return _arr2; }
}
