Michael Dürig commented on JCR-2415:
------------------------------------

Coincidentally I did just about the same thing yesterday and it seems we 
arrived at more or less the same point independently. However, your work seems 
to be more mature than mine. 

It would certainly be nice to get to the point where Lucene 3.0.x could be 
used. Therefore we need to get rid of SortComparatorSource/ScoreDocComparator 
which have been removed in Lucene 3. It doesn't seem to be a simple matter of 
switching to FieldComparatorSource/FieldComparator since these do not compose 
(i.e. for implementing upper/lower case sorting on top of an existing 
comparator). 

I just switched to your branch and will see what I can do.

> Lucene 3.0 was released on 2009/11/25. They migrated to Java 1.5 as 
> Jackrabbit is doing with 2.0. Also they added some new optimizations. It 
> would be nice if Jackrabbit could switch to the new lucene version too.
