Uwe Schindler commented on LUCENE-5850:
---------------------------------------
OK, so in my opinion we should resolve this issue, because it is a duplicate of
LUCENE-5537. The problem [~simonw] complained about was already fixed there. We
should create a new issues about:
- Should we write full bugfix version to index, not just "x.y" and "x.y.0.z"?
(the attached patch handles this, I would just revert VersionparserLeniently())
-> we agreed on that, but the issue should be committed in a new issue.
- merge all Version comparators and solely use Version enum? Maybe replace
Version enum by something else (hierarchical?)
> Constants#LUCENE_MAIN_VERSION can have broken values

> Constants#LUCENE_MAIN_VERSION is set to the Lucene Main version and should
> not contain minor versions. Well this is at least what I thought and to my
> knowledge what the comments say too. Yet in for instance 4.3.1 and 4.5.1 we
> broke this such that the version from SegmentsInfo can not be parsed with
> Version#parseLeniently. IMO we should really add an assertion that this
> constant doesn't throw an error and / or make the smoketester catch this. to
> me this is actually a index BWC break. Note that 4.8.1 doesn't have this
> problem...
