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, 383 ms]
(4) NO


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

(0)
Obligation:
need to prove termination of the following program:
package simple.ex06;

public class Ex06 {

	public static void loop(int i) {
		while (i >= -5 && i <= 5) {
			if (i > 0) {
				i--;
			}
			if (i < 0) {
				i++;
			}
		}
	}
}


package simple.ex06;

public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
        int value = args[1].length();
        if (args[0].length() % 2 == 0) {
            value = -value;
        }
		Ex06.loop(value);

	}

}
