 * CWE: 789 Uncontrolled Memory Allocation
 * BadSource: max_value Set data to a hardcoded value of Integer.MAX_VALUE
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: HashMap
 *    BadSink : Create a HashMap using data as the initial size
 * Flow Variant: 45 Data flow: data passed as a private class member variable from one function to another in the same class
