Subject RE: [Vote] Apache Lucene.Net 4.8.0-beta00001

It causes a crash under highly concurrent scenarios, and will most likely affect all of the
file-system directories. It does not affect the index, otherwise some of the index tests would
have detected it. Peter van Ginkel (the user who discovered it) has been kind enough to contribute
a test that fails most of the time if the concurrency bug exists, but before this none of
our tests have been able to detect it. Peter also has been able to work around this bug, and
I have asked him to post the workaround at:

It is a severe bug. Is it our most severe bug? Maybe. Is it severe enough to destroy our reputation?
Being that there is a bootleg copy out there that is already doing just that (that is versioned
as production-ready and already has this bug), I would say we are better off releasing with
the bug than not. If we didn't have that issue to contend with, I would agree with Itamar
that we should re-roll the release.

Presscott, Stefan, Simon, WDYT?

As you may know I'm not a user of Lucene.Net myself, so take my opinion with a grain of salt.

I'm not sure about the impact of the bug. If you run into it, will it make your application
crash or wil it destroy the index? In the later case I'd say we should re-roll the release.
Otherwise we should publish the release, fix the bug and plan for a second beta soon.
