[jira] [Created] (ARROW-7405) [Java] ListVector isEmpty API is incorrect

Ji Liu created ARROW-7405:
-----------------------------

             Summary: [Java] ListVector isEmpty API is incorrect
                 Key: ARROW-7405
                 URL: https://issues.apache.org/jira/browse/ARROW-7405
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java
            Reporter: Ji Liu
            Assignee: Ji Liu


 Currently {{isEmpty}} API is always return false in {{BaseRepeatedValueVector}}, and its subclass {{ListVector}} did not overwrite this method.

This will lead to incorrect result, for example, a {{ListVector}} with data [1,2], null, [], [5,6] should get [false, false, true, false] with this API, but now it would return [false, false, false, false].
