termination of the given Bare JBC problem could be disproven:

(0) Bare JBC problem
(1) BareJBCToJBCProof [EQUIVALENT, 96 ms]
(2) JBC problem
(3) JBCToGraph [EQUIVALENT, 263 ms]
(4) JBCTerminationGraph
(5) JBCNonTerm [COMPLETE, 513 ms]
(6) NO

(0)
Obligation:
need to prove termination of the following program:
package simple.ex07;

public class Ex07 {

	public static void loop(int i) {
		while (true) {
			if (i > 0) {
				i--;
			}
			if (i < 0) {
				i++;
			}
		}
	}
}

            value = -value;
        }
		Ex07.loop(value);

	}
