[jdom-interest] jdom and dom4j

The first release of dom4j was based on JDOM code.  If you don't believe
me, I can dig up references.  That defines it as a fork.  


Over time the codebases have of course diverged.  Yet looking through
the dom4j I do still see remnants of the old JDOM code.  I don't think
dom4j ever did a clean room restart.  

Hmm, yet I don't see any reference to the JDOM license as is required. 
Even if they rewrote basically all the code over time, I'm pretty sure
it's still a derived work legally speaking.  That puts them in violation
of the JDOM license since they removed the required JDOM copyright
notice and the other license clauses.
