I'll open an issue for this; I think it should block 4.10.1.

Also if there are going to be checks against this, if its really going
to become the primary entry point for deciding the version of a
segment and what exception to throw and so on, then I strongly
disagree with string encoding.
In my opinion we already have such a scheme figured out (CodecUtil
methods) with exception handling and everything...

I agree, can we remove all the checks here? They are bogus in a few ways:
1. Version.parse claims its forwards compatible, but the ctor throws
these exceptions.
2. These exceptions are thrown without indicating what the actual value was.
3. These exceptions are thrown with no context (the toString of the
input file itself).
So, I don't think Version should do these checks, at least, if it
wants to do them, it needs to step up to the plate and do them
correctly.

Especially, as I said in my previous email: ist in my opinion bad to throw IllegalArgumentException on version's parse if it is a vlaid version.
I tried it locally and created an Index with version 6.0 written to disk (I hacked it). If I try top open it with IndexReader of Lucene 4, so it should throw IndexTooNewException! But in fact it did not, because Version.parse() failed earlier! So we are inconsistent with Exceptions! It should in fact really throw IndexFormatTooNewException!
In my opinion, the bounds checks in the Version ctor should be "optional", so when parsing versions from index files we have a chance to throw the "correct exception".

I think it makes sense to be defensive here and have the check in two places.
This also guards against any future changes to Version that somehow
allow this ... it sure look like Version can't ever be created in an
"out of bounds" state today, but who knows tomorrow ...

Hi,
I am not sure, if the hard checks in the ctor are future-proof: Currently we detect versions < 3.0 early when reading segments, because they have some signatures that identify them as 3.x or earlier, so we can “correctly” throw IndexFormatTooOldException (because we never try to parse a version). If we later (e.g. in version 5 or 6) drop support for those older versions, how can we correctly throw “IndexFormatTooOldException”, if the parsing of a version written to segment fails with IAE during parsing? In addition, we can never throw IndexFormatTooNewException, if we get (some time in the future) with the current 4.10 version - as released last month - such an value in a future index file. The user would get an exception, but the wrong one.
Therefore, I would not restrict versions soo much in the ctor. Ideally we would throw the IndexFormatTooOld/New in ctor already (but it is an IOException, so it does fit the use-case to be thrown while parsing).
Uwe

How would the Version be constructed with an invalid major version, given
this exact check in the constructor (and the fact that the only way to
construct is through Version.parse)?
