Better to use Java NIO2 to read the file content:

List<String> lines = Files.readAllLines(Paths.get("path-to-file"), charset);

It's allow to avoid using while loop with redundant readers.

What is the OS installed on failed notebooks?

Also try to change folder name using '_' instead of space. I think it's the main reason of the issue.

If the file is outside the jar file, you should put an absolute path, or the "csv fajlok" folder should be in the same folder where you execute the jar file.

If the file is inside the jar file, you cannot access to it as a file but as a Stream, with the method Class.getResourceAsStream(String path).
