[jira] [Commented] (LUCENE-3658) NRTCachingDir has invalid asserts
(if same file name is written twice)

-------------------------------------
thanks for looking at these 2 tests, now you see why I bailed on them!

> Normally Lucene is write-once (except for segments.gen file, which NRTCachingDir never caches), but in some tests (TestDoc, TestCrash) we can write the same file more than once.
> I don't think NRTCachingDir should have these asserts, and I think on createOutput it should remove any old file if present.
> I also found & fixed a possible concurrency issue (if more than one thread syncs at the same time; IndexWriter doesn't ever do this today but it has in the past).
