Hi I am playing with generics a suddenly found a issue where i am getting compile time error :

Type mismatch: cannot convert from element type Object to String

import java.util.*;

public class A<T> {
    private final T first;

    public A(T first) {
        this.first = first;

    }
    public List<String> stringList() {
        return Arrays.asList(String.valueOf(first));
    }

    public static void main(String[] args) {
        A p = new A<Object>("TEST");
        for (String s : p.stringList())
            System.out.print(s + " ");
    }
}

I am unable to understand this behavior as String is Object and compiler should understand that, can someone explain this?
