> Using jdbc-all built right before DRILL-3589 commit works fine, so the problem seem to
be related to the changes in DRILL-3589
> Here is the program I'm running:
> {code}
> import java.sql.Connection;
> import java.sql.DriverManager;
> import java.sql.ResultSet;
> import java.sql.Statement;
> public class SimpleJdbc {
>   public static void main(String[] args) throws Exception {
>     Class.forName("org.apache.drill.jdbc.Driver").newInstance();
>     Connection conn = DriverManager.getConnection("jdbc:drill:");
>     Statement stmt = null;
>     ResultSet rs = null;
>     try {
>       stmt = conn.createStatement();
>       rs = stmt.executeQuery("SELECT employee_id FROM cp.`employee.json`");
>       while (rs.next()) {
>         System.out.println(rs.getObject(1));
>       }

>         stmt.close();
