Hi,

The reason why you cannot see the dependency is probably that you looked
at the binary package eclipse.  The package actually depending on
liblucene2-java is eclipse-platform, which is (also) built from a source
package called eclipse. :)

The reason why we need to modify eclipse is because we got some
non-trivial with plugins not being loaded in eclipse if some
dependencies where upgraded.  This lead to #587657, which started out
with a problem sat4j, but we later learned lucene2 produced a similar
effect (e.g. see message #125).
  The issue is particularly annoying as it is non-trivial to debug why
this happens, because eclipse silently degrades itself in most cases and
the rest it says something like "Cannot open editor
org.eclipse.cdt.editor.CEdtior, class not found".  Neither helps the
user to realise they have to manually fix a file that is out of date.
