> [Java] JsonFileReader doesn't intialize some vectors approperately
> -------------------------------------------------------------------
>
> Key: ARROW-1431
> URL: https://issues.apache.org/jira/browse/ARROW-1431
> Project: Apache Arrow
> Issue Type: Bug
> Reporter: Li Jin
>
> One example is for ListVector, the JsonFileReader sets the validity, offset
> and data, but doesn't set `lastSet` variable in the ListVector instance.
> ArrowFileReader works correct before it invokes `loadFieldBuffers` and
> intialize `lastSet` correctly:
> https://github.com/apache/arrow/blob/master/java/vector/src/main/java/org/apache/arrow/vector/complex/ListVector.java#L120
> This doesn't break integration tests but can cause weird bugs when people
> call methods on the vector read from json.
