 * @description
 * CWE: 190 Integer Overflow
 * BadSource: max Set data to the max value for long
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: square
 *    GoodSink: Ensure there will not be an overflow before squaring data
 *    BadSink : Square data, which can lead to overflow
 * Flow Variant: 71 Data flow: data passed as an Object reference argument from one method to another in different classes in the same package
