It's the covariant return types that we most want, and that JDK 1.4
doesn't provide. This is where you can override a method and return a
more specific type than the superclass returns.
Also, it's not source maintenance I'm really worried about. It's having
two versions of jdom.jar in the world. What happens when your app uses
libraries, one of which depends on JDOM regular and one of which depends
on JDOM 5? It doesn't work. This is why we'd probably need to use new
packages containing the version within the package name.
