 * CWE: 191 Integer Underflow
 * BadSource: min Set data to the max value for short
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: decrement
 *    GoodSink: Ensure there will not be an underflow before decrementing data
 *    BadSink : Decrement data, which can cause an Underflow
 * Flow Variant: 61 Data flow: data returned from one method to another in different classes in the same package
