 * CWE: 129 Improper Validation of Array Index
 * BadSource: connect_tcp Read data using an outbound tcp connection
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: array_write_no_check
 *    GoodSink: Write to array after verifying index
 *    BadSink : Write to array without any verification of index
 * Flow Variant: 53 Data flow: data passed as an argument from one method through two others to a fourth; all four functions are in different classes in the same package
