-----------------------------
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].
