> Hakim's analysis:
> {code}
> More details about the NPE, actually it's an IllegalArgumentException: what
> happens is that during planing no file meets the wildcard selection and the
> query should fail during planing with a "Table not found" message, instead
> execution starts and the scanner fail because no file was assigned to them
