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, 204 ms]
(4) NO


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

(0)
Obligation:
need to prove termination of the following program:
public class Ex02 {

    public static void loop(int i) {
	if (i > 0) {
	    if (i != 5) i--;
	    loop(i);
	}
    }

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



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

(1) BareJBCToJBCProof (EQUIVALENT)
initialized classpath
----------------------------------------

(2)
Obligation:
need to prove termination of the following program:
public class Ex02 {

    public static void loop(int i) {
	if (i > 0) {
	    if (i != 5) i--;
	    loop(i);
	}
    }

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



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

(3) JBCNonTerm (COMPLETE)
Constructed a run with a repetition. States 3 and 10 are repetitions (when considering only the interesting positions [lv_0_0]).
