[jira] [Created] (LUCENE-8437) CheckIndex should not duplicate SegmentInfos serialization

Adrien Grand created LUCENE-8437:
------------------------------------

             Summary: CheckIndex should not duplicate SegmentInfos serialization
                 Key: LUCENE-8437
                 URL: https://issues.apache.org/jira/browse/LUCENE-8437
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Adrien Grand


CheckIndex tries to read the segments file to provide more information about the problem, but it gets almost everything wrong: it reads an int which based on comments and error messages is either the format or the version but this is actually the magic number of the codec header. It looks like this code is about10 years old and hasn't been updated when we added checksums to index files. SegmentInfos does a better job at detecting issues nowadays, so these manual checks can be removed.
