[jira] [Updated] (ARROW-11788) [Java] Appending Empty List Vector
yields NPE
[ https://issues.apache.org/jira/browse/ARROW-11788?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nick Bruno updated ARROW-11788:
-------------------------------
Description:
Attempting to append a list vector that is empty to another vector that is also empty using VectorAppender raises an NPE. Instead, it should just skip processing and do nothing.
