 * CWE: 190 Integer Overflow
 * BadSource: Property Read data from a system property
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: add
 *    GoodSink: Ensure there will not be an overflow before adding 1 to data
 *    BadSink : Add 1 to data, which can cause an overflow
 * Flow Variant: 72 Data flow: data passed in a Vector from one method to another in different source files in the same package
