[jdom-interest] jdom 2.0 with generics

[Olivier Jaquemet]

To that regard, I like the approach taken by several libraries when 
making important change with backward compatibility, specially for 
Generics.
They change the package name ! That way, the only thing required for the 
developper wanting to use the new version is a simple modification of 
the import directive + the generics modification is required. And code 
using the older library can be left untouched.

For example, apache commons lang 3.0 which has been release two days ago 
is using this approach.
import org.apache.commons.lang -> import org.apache.commons.lang3
It allows older version of the library to seat next to the new one 
without any glitches.

So +1 for JDom 2 with generics with a package name change.
