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, 176 ms]
(4) NO

(0)
Obligation:
need to prove termination of the following program:
/**
 * Method iter() (and hence also main()) diverges.
 */

public class TestJulia6 {

    private static TestJulia6 last;

    private TestJulia6 f;

    private TestJulia6() {

(2)
Obligation:
need to prove termination of the following program:
/**
 * Method iter() (and hence also main()) diverges.
 */

public class TestJulia6 {

    private static TestJulia6 last;

    private TestJulia6 f;

    private TestJulia6() {
        last = this;
    }

    public static void main(String[] args) {
        TestJulia6 l = new TestJulia6();
        l.f = last;
        last.iter();
    }

    private void iter() {
        if (f != null)
            f.iter();
    }
}



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

(3) JBCNonTerm (COMPLETE)
Symbolic evaluation of method public static main([Ljava/lang/String;)V never reaches a method end (by explicit return or exception).

As this is the main method, we can conclude non-termination of the input program.
