Adrien Grand commented on LUCENE-9356:
--------------------------------------
This test does try to account for CRC32 collisions, it runs checksumEntireFile
after doing a byte flip, and then returns if checksumEntireFile returned
successfully, which would indicate a CRC32 collision? That said, I agree with
your suggestions and opened https://github.com/apache/lucene/pull/876.

> Remaining Estimate: 0h

> We already have tests that file truncation and modification of the index
> headers are caught correctly. I'd like to add another test that flipping a
> byte in a way that modifies the checksum of the file is always caught
> gracefully by Lucene.
