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, 257 ms]
(4) NO

(0)
Obligation:
need to prove termination of the following program:
public class NO_04 {
    public static void main(String args[]) {
        for (int i = 0; i < 100; i++) {
	    int a = i+2;
            for (int j = 0; j < a; j++)
		for (int k = i+j+3; k >= 0; k--) {
		    int b = i+j+k+4;
		    for (int l = 0; l < b; l++)
			for (int m = i+j+k+l+1000; m >= 0; m -= 0);
		}
	}
