Bug in ContentValuesUtil

[elincognito]

public static void putMapped(String key, Map<String, String> map, ContentValues values, String value) {
if(map == null || !map.containsKey(key)) {
values.put(key, value);
}

    String alias = map.get(key);

    if(alias != null) {
        values.put(alias, value);
    }
}

if map is null then a return is required otherwise
String alias = map.get(key);

will throw a NullPointerException
