IntegerRange violates assertion when establishing a constraint

Using org.opalj.ai.domain.l1.DefaultIntegerValuesDomain

Analyzing

    public static void demonstratesIntFailure(int size) throws Exception {
        for (int i = 0; i < size; i++) {
            ;
        }
        for (int i = 0; i < size; i++) {
            ;
        }
    }

leads to a violated assertion: assert(lowerBound <= upperBound)
