 * CWE: 369 Divide by zero
 * BadSource: PropertiesFile Read data from a .properties file (in property named data)
 * GoodSource: A hardcoded non-zero number (two)
 * Sinks: divide
 *    GoodSink: Check for zero before dividing
 *    BadSink : Dividing by a value that may be zero
 * Flow Variant: 73 Data flow: data passed in a LinkedList from one method to another in different source files in the same package
