termination of the given Bare JBC problem could be disproven:

(0) Bare JBC problem
(1) BareJBCToJBCProof [EQUIVALENT, 96 ms]
(2) JBC problem
(3) JBCNonTerm [COMPLETE, 623 ms]
(4) NO

Obligation:
need to prove termination of the following program:
public class List {
    public int head;
    public List tail;

    public List(int h, List t) {
	head = h;
	tail = t;
    }
}

public class Test13 {
    private static List l1, l2;

    public static void main(String[] args) {
	List l = new List(13, null);
	List start = l;

	for (int i = 0; i < args.length + 1; i++) 
	    l = l.tail = new List(11, null);

	l1 = l;
