I'm guessing this mostly happens during serialization to and from strings.
One programmer does String.valueOf(x) instead of x.toString() to prevent NullPointerExceptions.
This works pretty well until the next guy does x == null || x.equals("null") because "null"s pop up in UI.
At this point this is irreversible as nobody can tell what is null and what is "null". |
