[Java][FlightSQL] Column Duplication When Selecting from no result record in Arrow Flight SQL JDBC Driver

[mingnuj]

Describe the bug, including details regarding any error messages, version, and platform.

I encountered an issue when working with Arrow Flight SQL, and I would appreciate your help.

I created a test_table with the following columns:

CREATE TABLE default.public.test_table (col1 int);

When I run a SELECT * query without inserting any data into the table, the columns appear duplicated. I get the following output:

I am developing the database myself, using Rust and connecting through FlightSQL. When executing SELECT clause and the table is empty, I handle this by returning an endpoint with empty endpoint in the get_flight_info method.

This did not occur in Arrow Flight SQL JDBC Driver versions prior to 15.0.0, but it started happening with version 15.0.0.
