Apologize, I just wish to cover the basics.  Have you check which user you
use to execute the Java program?  And could you kindly check if that user
has the rights to execute AtomicParsley?  Maybe set file permission to 755
or something.

I think that is expected for Generics if I am not mistaken.  The Foo in
List is just for compile time.  On runtime, it just knows that it is a
List, and do not know it is a list of Foo.

I think CSVParser is strict and may not work for both LF and CRLF.  Maybe
try to scan the file first and see if line ending is lf or crlf, and then
use a corresponding CSVParser instance that can handle each case.
