 * CWE: 129 Improper Validation of Array Index
 * BadSource: Property Read data from a system property
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: array_read_no_check
 *    GoodSink: Read from array after verifying index
 *    BadSink : Read from array without any verification of index
 * Flow Variant: 68 Data flow: data passed as a member variable in the "a" class, which is used by a method in another class in the same package
