I think that for lucene2 and current solr you should leave the packaging
as-is as this reflects the way the upstream projects where managed prior
to recent changes.

I think we should maintain support for lucene2 for the time being in
which case having liblucene3-java does make sense which some good
conflicts (but they may not be required).

FYI packaging on lucene3 has been started in Debian:

 svn://svn.debian.org/svn/pkg-java/trunk/lucene3/

However this has been stalled for some time and the ITP owner has just
stood down from packaging in Debian.  Whatever we do in Ubuntu we should
make sure we are collaborating with the Debian Java - the Java delta
between Ubuntu and Debian is minimal and we should try to keep it that
way.

I'd be interested on working on this as well; I want to try an get
OpenGROK packaged and an update for solr would be no bad thing.

Cheers

James
