Subject [jira] [Created] (CLI-264) Short/Long options can be called using either '-' or '--' hyphens with no limitation

Adrien CABARBAYE created CLI-264:
------------------------------------

             Summary: Short/Long options can be called using either '-' or '--' hyphens with
no limitation
                 Key: CLI-264
                 URL: https://issues.apache.org/jira/browse/CLI-264
             Project: Commons CLI
          Issue Type: Bug
          Components: CLI-1.x
    Affects Versions: 1.3.1
            Reporter: Adrien CABARBAYE


When using DefaultParser, any options can be accessed using either '-' or '--' as a prefix
and so regardless whether they have been defined as short or long.

the problem is in handleToken:

237        else if (token.startsWith("--"))
238        {
239            handleLongOption(token);
240        }
241        else if (token.startsWith("-") && !"-".equals(token))
242        {
243            handleShortAndLongOption(token);
244        }

Some logic should be added so that if an option has been defined as short  (e.g. -h), if --h
is used, for instance, in the command line, an exception should be raised. Similarly for long
options which are being called using only '-' instead of '--' as a prefix, an exception should
also be fired.
