The problem with autounboxing null values can be really annoying. In your example it's a combination of ternary operator result type inferring and autounboxing (the JLS should be consulted why it behaves like that)

But generally, you should try to avoid using wrapper types. Use int instead of Integer. If you need a special value meaning "no result", then you can use Integer.MAX_VALUE for example.
