termination of the given Bare JBC problem could be disproven:

(0) Bare JBC problem
(1) BareJBCToJBCProof [EQUIVALENT, 97 ms]
(2) JBC problem
(3) JBCNonTerm [COMPLETE, 145 ms]
(4) NO


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

(0)
Obligation:
need to prove termination of the following program:
public class TerminatorRec03 {
	public static void main(String[] args) {
		f(args.length);
	}

	public static void f(int x) {
		if (x == 0) {
			f(1);
		} else {
			f(0);
		}
	}
}



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

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

(2)
Obligation:
need to prove termination of the following program:
public class TerminatorRec03 {
	public static void main(String[] args) {
		f(args.length);
	}

	public static void f(int x) {
		if (x == 0) {
			f(1);
		} else {
			f(0);
		}
	}
}



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

(3) JBCNonTerm (COMPLETE)
Constructed a run with a repetition. States 3 and 11 are repetitions (when considering only the interesting positions [lv_0_0]).
