> It's because the object reuse. For the below schema:
> {code:java}
> create table sink {
> col1 int,
> col2 array<int>
> }{code}
> if col2 is null, then the reused object will be {{NullNode}}. for the next
> record, if it's not null, we will cast the reused object {{NullNode}} to
> {{ArrayNode}}, which will throw cast exception.
