[jira] [Created] (CLI-274) Option parser type EXISTING_FILE_VALUE not check file existing

["Béla Schaum (JIRA)" <ji...@apache.org>]

Béla Schaum created CLI-274:
-------------------------------

             Summary: Option parser type EXISTING_FILE_VALUE not check file existing
                 Key: CLI-274
                 URL: https://issues.apache.org/jira/browse/CLI-274
             Project: Commons CLI
          Issue Type: Bug
          Components: Parser
            Reporter: Béla Schaum
            Priority: Minor


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:
