Ayelet Morris commented on CALCITE-2795:
----------------------------------------
* What version(s) of Avatica did you observe to work correctly? we upgraded
to Calcite 1.18 and Avatica 1.13
* What version(s) of Avatica did you observe this error? we didn't try to
upgrade to other versions lately
* What is the code you ran which caused this?
POJO:
public class TypeWithList {
private String id;
private List<String> list;
public TypeWithList(String id, List<String> list) {
this.id = id;
this.list = list;
}
public String getId() {
return id;
}
public List<String> getList() {
return list;
}
}
Test:
@Test
@Ignore("List functionality is broken since upgrade from 1.11 => 1.18")
public void testSelectWithList() {
List<String> list = new LinkedList<>();
list.add("a");
list.add("b");
ist.add("a");
myDb.write(new TypeWithList("1", list));
CalciteAssert.that()
.with(connectionFactory)
.query("SELECT * FROM TypeWithList")
.returnsUnordered("id=1; list=[a, b, a]");
}
Thanks for your help.
Sorry it took me so long to answer.

> Project: Calcite
> Issue Type: Bug
> Components: avatica
> Affects Versions: 1.17.0, 1.18.0
> Reporter: Ayelet Morris
> Priority: Blocker
>
> I created a simple POJO that has an id and a list and created a simple select
> query from it, I received the following exception, it seems that in previous
> versions (we used avatica 1.9 with calcite 1.11 before this upgrade) the list
> type was detected as "OTHER" type and the query worked, now it is marked as a
> Scalar but somehow finds its way to the "array" type of the types switch,
> then when trying to parse the column TYPE it fails (it doesn't even try to
> fetch the list itself)
