Robert Muir commented on LUCENE-5850:
-------------------------------------

It is intentional that this isnt changed:
{noformat}
We should never change index format with minor versions, so it should always be x.y or x.y.0.z
for alpha/beta versions!

> 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...
