termination of the given Bare JBC problem could be proven:

(0) Bare JBC problem
(1) BareJBCToJBCProof [EQUIVALENT, 96 ms]
(2) JBC problem
(3) JBCToGraph [EQUIVALENT, 159 ms]
(4) JBCTerminationGraph
(5) TerminationGraphToSCCProof [SOUND, 0 ms]
(6) TRUE


----------------------------------------

(0)
Obligation:
need to prove termination of the following program:
public class Random {
  static String[] args;
  static int index = 0;

  public static int random() {
    String string = args[index];
    index++;
    return string.length();
  }
}


public class SharingPair {
	SharingPair next;

	public static void main(String[] args) {
		Random.args = args;
		SharingPair one = new SharingPair();
		SharingPair two = new SharingPair();
		SharingPair cur;
		int i = Random.random();
		if (i == 0) {
			one.next = two;
			cur = one;
		} else {
			two.next = one;
			cur = two;
		}

		while (true) {
			if (i == 0) {
				one.next = new SharingPair();
				cur = cur.next;
			} else {
				two.next = new SharingPair();
				cur = cur.next;
			}
		}
	}
