           Summary: argument defaults prevent commandline usage.
           Product: Commons
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: CLI
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: aks@decisionsoft.co.uk


I have found a bug in the following scenario:

You have an option which can take a single argument which in turn has a default
value. You supply a value on the command line which is intended to override
this default however as the CommandLine already has a value for this Option,
this second value is not allowed and the command line cannot be parsed.

I have created a patch which adds a method to WritableCommandLine and its Impl
which allows you to retrieve the undefaulted values for an Option. I have then
changed ArgumentImpl to use this method to determine the argument count
