Emmanuel Bourg commented on CLI-246:
------------------------------------

Thank you for the report, could you try with the DefaultParser on the trunk and see if it
works please?

>                 Key: CLI-246
>                 URL: https://issues.apache.org/jira/browse/CLI-246
>             Project: Commons CLI
>          Issue Type: Bug
>          Components: CLI-1.x
>    Affects Versions: 1.2
>         Environment: Windows 64-bit
>            Reporter: Pierre-Luc Lacroix
>            Priority: Minor

> Title might be hard to understand, but basically:
> Arguments:
> String [] cli = {"-cc", "-ccc", "-c"};
> Options:
> Options opts = new Options();
> opts.addOption(OptionBuilder.create("cc"));
> opts.addOption(OptionBuilder.create("c"));
> As you can see, "-ccc" is an extra unrecognized argument.
> When you try to parse it:
> CommandLineParser parser = new GnuParser();
> CommandLine line = parser.parse(opts, cli, true);
> Content on line:
> args: [cc, -c]
> line: [[ option: cc  :: null ], [ option: c  :: null ]]
> I would expect:
> args: [-ccc]
> line: [[ option: cc  :: null ], [ option: c  :: null ]]
> Wrote a few unit tests (3rd one fails):
> {code:title=UnitTest.java|borderStyle=solid}
