At first I thought you might want to add fields to a subclass for 
logging, or caching, stuff like that, while still wanting to inherit the 
constructors. Then I checked some code for a project I wrote in Java and 
always when the subclass had new fields it defined a different 
constructor, and the logging fields were static. So I think that most of 
the time you'd want to inherit the constructors when you don't define 
new fields.
