 * CWE: 197 Numeric Truncation Error
 * BadSource: PropertiesFile Read data from a .properties file (in property named data)
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: to_byte
 *    BadSink : Convert data to a byte
 * Flow Variant: 22 Control flow: Flow controlled by value of a public static variable. Sink functions are in a separate file from sources.
