I agree -- go forward with backwards compatibility.

To that regard, I like the approach taken by several libraries when
making important change with backward compatibility, specially for
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.
