Uwe Schindler commented on LUCENE-2484:
---------------------------------------
So after hours of waiting:
- Lucene Core, Contrib is fine
- Modules fine
- Solr core works
- *Solr carrot2 is broken and this is not fixable!*
Its broken by itsself:
The contrib module for carrot clustering depends on carrot, but carrot itsself
depends on an older version of Lucene! We only have the binary, so we cannot
fix it:

We cannot move forward in breaking backwards in trunk, so I suggest to disable
this contrib in trunk! We can only support it if, it moves to Lucene/Solr in
complete and we have the source code in solr's SVN.
Thoughts?
> Remove deprecated TermAttribute from tokenattributes and legacy support in
