Jukka Zitting commented on JCR-788:
-----------------------------------

Please do share a patch with your changes. It's always easier to judge a change 
if the actual code is available. BTW, would the modified class still work with 
Lucene 2.0? I also assume that Lucene 2.1 is compatible with indexes created 
with 2.0.

I agree that we should try to keep up with Lucene upgrades, but on the other 
hand I would not want to force too frequent dependency changes on users. If the 
change works with Lucene 2.0, then existing users wouldn't need to upgrade 
their dependencies. If not, then the upgrade procedure needs to be documented 
in the release notes.

If there is no immediate demand for the upgrade, I would rather wait until 
Jackrabbit 1.3 is branched before doing this.
