------------------------------------

             Summary:    Integer remainder modulo 1 problem in /core/src/java/org/apache/lucene/index/CheckIndex.java
                 Key: LUCENE-8077
                 URL: https://issues.apache.org/jira/browse/LUCENE-8077
             Project: Lucene - Core
          Issue Type: Bug
          Components: core/index
    Affects Versions: 7.1
            Reporter: Xiaoshan Sun


At  /core/src/java/org/apache/lucene/index/CheckIndex.java: 2198 
The branch condition :
{code:java}
(i % 1 == 0)
{code}
is always true. 
Did you mean (exp & 1) or (exp % 2) instead?


The related code is show below:

{code:java}
2198:        if (i % 1 == 0) {
          int doc2 = it2.nextDoc();
          if (doc != doc2) {
            throw new RuntimeException("dv iterator field=" + field + ": doc=" + doc + " was not found through advance() (got: " + doc2 + ")");
          }
          if (it2.docID() != doc) {
            throw new RuntimeException("dv iterator field=" + field + ": doc=" + doc + " reports wrong doc ID (got: " + it2.docID() + ")");
          }
        }
      }
{code}
