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, 284 ms]
(4) NO


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

(0)
Obligation:
need to prove termination of the following program:
public class WhileNestedOffset {

    public static void increase_aux(int j) {
	if (j > 5) increase_aux(j + 1);
    }

    public static void increase(int i) {
	if (i < 10) {
	    increase_aux(i);
	    increase(i + 1);
	}
    }

    public static void main(String[] args) {
	increase(args.length);
    }
}
