It appears that this issue is due to the Turkish locale.

I believe this is due to how Calcite is handling locales. [~risdenk], curious
if you see the same thing, which is that this in the Calcite code.
[~steve_rowe], if it does turn out this is a Calcite issue I'll log an issue on
the Calcite site and submit a patch. In the meantime is there a way to suppress
the Turkish locale in the tests?

> Integrate Apache Calcite into the SQLHandler
> --------------------------------------------
>
> Key: SOLR-8593
> URL: https://issues.apache.org/jira/browse/SOLR-8593
> Project: Solr
> Issue Type: Improvement
> Components: Parallel SQL
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Fix For: 6.5, master (7.0)
>
> Attachments: SOLR-8593.patch, SOLR-8593.patch, SOLR-8593.patch

>
> The Presto SQL Parser was perfect for phase one of the SQLHandler. It was
> nicely split off from the larger Presto project and it did everything that
> was needed for the initial implementation.
> Phase two of the SQL work though will require an optimizer. Here is where
> Apache Calcite comes into play. It has a battle tested cost based optimizer
> and has been integrated into Apache Drill and Hive.
> This work can begin in trunk following the 6.0 release. The final query plans
> will continue to be translated to Streaming API objects (TupleStreams), so
> continued work on the JDBC driver should plug in nicely with the Calcite work.
