Ji Liu created ARROW-7467:
-----------------------------

             Summary: [Java] ComplexCopier does incorrect copy for Map nullable info
                 Key: ARROW-7467
                 URL: https://issues.apache.org/jira/browse/ARROW-7467
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java
            Reporter: Ji Liu
            Assignee: Ji Liu


The {{MapVector}} and its 'value' vector are nullable, and its {{structVector}} and 'key' vector are non-nullable.

However, the {{MapVector}} generated by ComplexCopier has all nullable fields which is not correct.
