Do not mind, I can't tell you what I have already seen at my workplace from *professional* programmers ;-) btw, a nice example how dangerous auto-boxing is: Map<Short, Object> map = new HashMap<Short, Object>(); // fill the map with objects, keys in the range 1..10 ... // get the object with key 3 Object o = map.get(3); o == null or not?
