clintropolis opened a new pull request #12244: URL: https://github.com/apache/druid/pull/12244
### Description Split out bug fixes from #12241 in case that PR is too noisy. This PR fixes some issues uncovered while working on that other PR, related to null coercion with multi-value string array expressions, similar to the bugs fixed https://github.com/apache/druid/pull/12078 (and controlled by the flag https://github.com/apache/druid/pull/12210) This fix exists entirely within that other PR, though there is a subtle difference between the output of `CalciteMultiValueStringQueryTest.testMultiValueListFilterComposed` due to differences in behavior between the falllback `filter` expression and the native `ListFilteredVirtualColumn` (`filter` produces 0 length arrays for rows which do not match, while `ListFilteredVirtualColumn` considers these values as `null` which is consistent with the behavior of other multi-value string dimension selectors). Should the other PR be merged before this one, this can be closed (and likewise will fix up the other PR should this one be merged first). <hr> This PR has: - [ ] been self-reviewed. - [ ] using the [concurrency checklist](https://github.com/apache/druid/blob/master/dev/code-review/concurrency.md) (Remove this item if the PR doesn't have any relation to concurrency.) - [ ] added documentation for new or modified features or behaviors. - [ ] added Javadocs for most classes and all non-trivial methods.
