             Summary: Index corruption: IndexOutOfBoundsException for doc values
                 Key: LUCENE-10159
                 URL: https://issues.apache.org/jira/browse/LUCENE-10159
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand


Since we upgraded Elasticsearch to a Lucene 9 snaspshot, we have seen test 
failures with the following stack trace. This looks like an issue with the 
Lucene90 DocValuesFormat.
