    Looking at this, I think we're doing to many things at once in this test. Why don't we
split this test up into to separate tests? One for `f<` and one for `g<`?

> When the user pass option type FileInputStream.class, I think the expected behavior for
the return value is the same type, which the user passed.
> Options options = new Options();
> options.addOption(Option.builder("f").hasArg().type(FileInputStream.class).build());
> CommandLine cline = new DefaultParser().parse(options, args);
> FileInputStream file = (FileInputStream) cline.getParsedOptionValue("f"); // it returns
"File" object, without check File exist.
> I attach a solution for it:
