[jdom-interest] JDom and Java5

Hi All.

I have ported JDom to use Java constructs throughout the code. I have
taken great pains to make the ported library as similar to the existing
one as possible. In fact, I believe that, in 99% of the cases, you will
probably be able to take the Java5 version and simply recompile your
code against the new Jar and have no problems.

At the same time, the code does a full implementation of Generics,
removes encumbrances required to support old Java versions (Java1.2,
etc.), and generally spruces up some of the ways that some things are done.

The porting has necessitated the rewrite of a number of core sections of
code (like ContentList), but there are performance improvements in there
too.

Obviously this has been an individual effort with all the pitfalls of
'single-mindedness' in there too. Any criticisms of the code will be
welcomed as the intention is to get a good result.

I believe all the nice things in Java5 are now available, especially
those using generics where all the methods return correctly typed data
like such that constructs like:

  Element root = document.getRootElement();
  for (Element child : root.getChildren()) {
    // do something with element child....
  }

are now possible.

At this stage, the work is done, and I am just trying to determine how
much interest there is in such a port.

I have set up an 'unreliable' server (it is my computer at home on a
residential cable-modem....) at git.tuis.net where you can:

browse a full repository of the three core JDom projects (jdom,
jdom-test, and jdom-contrib):
http://git.tuis.net/

read a README I put together:
http://git.tuis.net/jdom/README.Java5.txt

Download the actual source code (zipped or not):
http://git.tuis.net/jdom/src/
http://git.tuis.net/jdom/jdom.src.tar.gz

Download the actual jar:
http://git.tuis.net/jdom/jdom.jar

Review the API Docs:
http://git.tuis.net/jdom/apidocs/

Those wanting to access the repositories in git format can do so, or
those with CVS can access the same repository using the (git-based) CVS
proxies:

Thus, if you want to get a hold of the repositories, you can, using git:

git clone git://git.tuis.net/jdom.git
git clone git://git.tuis.net/jdom-contrib.git
git clone git://git.tuis.net/jdom-test.git

Or, using (slower) http protocol:

git clone http://git.tuis.net/git/jdom.git
git clone http://git.tuis.net/git/jdom-contrib.git
git clone http://git.tuis.net/git/jdom-test.git

Alternatively, you can use cvs (note the somewhat strange CVSROOTs)

cvs -d ":pserver:anonymous@(protected)
cvs -d ":pserver:anonymous@(protected)
-d jdom-contrib
cvs -d ":pserver:anonymous@(protected)
jdom-test

Depending on the levels of interest in this there will probably be the
requirement to migrate these repositories to a more reliable server,
etc. We'll cross that bridge if we get to it.
