[jira] [Created] (LUCENE-10017) Do not check footers on Lucene7x segments when throwing IndexFormatTooOld

Mike Drob created LUCENE-10017:
----------------------------------

             Summary: Do not check footers on Lucene7x segments when throwing IndexFormatTooOld
                 Key: LUCENE-10017
                 URL: https://issues.apache.org/jira/browse/LUCENE-10017
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/index
    Affects Versions: main (9.0)
            Reporter: Mike Drob


Ran into this while investigating how to improve the logging situation in SOLR-15516

When we throw an IndexFormatTooOldException when attempting to read a segment, we will read still attempt to read the footer since it is newer than 7x (which AFAIUI was the oldest version to support these footers?)

We should update that to only check footers for versions newer than 8x, otherwise we create a needless additional exception.
