Michael McCandless commented on LUCENE-2720:
--------------------------------------------
Both 3.x & trunk patches look great!
Maybe in the comment for SegmentInfo.version explain the "required"
format of the version? (Since it's a String). And eg note that we
don't track minor versions here? (Maybe just link to the same comment
for Constants.LUCENE_MAIN_VERSION).
> IndexWriter should throw IndexFormatTooOldExc on open, not later during

> Project: Lucene - Java

> Spinoff of LUCENE-2618 and also related to the original issue LUCENE-2523...
> If you open IW on a too-old index, you don't find out until much later that
> the index is too old.
> This is because IW does not go and open segment readers on all segments. It
> only does so when it's time to apply deletes, do merges, open an NRT reader,
> etc.
> This is a serious bug because you can in fact succeed in committing with the
> new major version of Lucene against your too-old index, which is catastrophic
> because suddenly the old Lucene version will no longer open the index, and so
> your index becomes unusable.
