Overloading function using varargs

This will not compile:

public class Methods
{

    public static void method(Integer... i)
    {
        System.out.print("A");
    }

    public static void method(int... i)
    {
        System.out.print("B");
    }

    public static void main(String args[])
    {
        method(7);
    }
}

This will compile and work:

public class Methods
{

    public static void method(Integer i)
    {
        System.out.print("A");
    }

    public static void method(int i)
    {
        System.out.print("B");
    }

    public static void main(String args[])
    {
        method(7);
    }
}

First and second example are very similar. First uses varargs, second not. Why one works, second not. 7 is primitive, so second method should be called in both cases. Is it normal behaviour?
