when trying to run the following code:

import java.util.*;

public class GenericsTest {
    public static void main(String args[]) {


        List<Integer> l = new ArrayList<Integer>();
        l.add(3);
        l.add(8);
// l.add("test");
        l.add(1);
        l.add(2);

        // Print list items
        int total = 0;
        for (Integer o : l) {
            System.out.println(o);
            total += o;
        }
        System.out.println("total = " + total);


    }
}

I get this error:

Exception in thread "main" java.lang.VerifyError: Bad type on operand
stack in method GenericsTest.main([Ljava/lang/String;)V at offset 93

changing the line:

    total += o;

to:

    total += o.intValue();

gets rid of the error, but I think the original should work as well.
