> The Javadoc comment below states that the parameter map "..., may not be 
> null":
>          /**
>           ..
>            * @param map  the map to convert to a Properties object, may not 
> be null
>            * @return the properties object
>            */
>           public static <K, V> Properties toProperties(final Map<K, V> map) {
>               Properties answer = new Properties();
>               if (map != null) {
>                   ...
>               }
>               return answer;
>           }
> However, the method return normally without throwing any exception when 
> called with null.
> Suggested Fixes:
> 1. Change "@param map  the map to convert to a Properties object, may not be 
> null" to "@param map  the map to convert to a Properties object, may be null"
> or
> 2. Remove "may not be null" from @param.
