 * @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: multiply
 *    GoodSink: Ensure there will not be an overflow before multiplying data by 2
 *    BadSink : If data is positive, multiply by 2, which can cause an overflow
 * Flow Variant: 81 Data flow: data passed in a parameter to an abstract method
