Add the following call here:

((FirebirdCallableStatement)stmt).setSelectable(true);

> stmt.setString(1, "Germany");
> ResultSet rs = stmt.executeQuery();
> while (rs.next())
> System.out.println(rs.getString(1));

The issue is that Jaybird has no idea whether the procedure is
selectable or executable when it is specified in the escaped syntax.
System tables also do not provide such information. So, it uses EXECUTE
PROCEDURE by default. For selectable procedures developer has to provide
a hint to Jaybird to use SELECT ... FROM call instead.
