 * CWE: 369 Divide by zero
 * BadSource: console_readLine Read data from the console using readLine
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: divide
 *    GoodSink: Check for zero before dividing
 *    BadSink : Dividing by a value that may be zero
 * Flow Variant: 22 Control flow: Flow controlled by value of a public static variable. Sink functions are in a separate file from sources.
