Emmanuel Bourg commented on CLI-137:
------------------------------------
This bug seems to be a blocker for projects willing to upgrade from 1.0 to 1.1.
Considering that the original behavior is right, and that the usage of CLI 1.0
[1] outweighs greatly the usage of CLI 1.1 [2], I think we'd better fix this.
The recommended upgrade path would be 1.0->1.2.

> The code:
> {code}
> import org.apache.commons.cli.CommandLine ;
> import org.apache.commons.cli.OptionBuilder ;
> import org.apache.commons.cli.GnuParser ;
> import org.apache.commons.cli.Option ;
> import org.apache.commons.cli.Options ;
> import org.apache.commons.cli.ParseException ;
> public class Trial {
> private void execute ( final String[] commandLine ) throws ParseException {
> final Options options = new Options ( ) ;
> options.addOption ( OptionBuilder.withLongOpt ( "flob" ).hasArg (
> ).create ( 'F' ) ) ;
> final CommandLine line = ( new GnuParser ( ) ).parse ( options ,
> commandLine ) ;
> String[] results = line.getOptionValues ( 'F' ) ;
> if ( results != null ) { for ( String s : results ) { System.out.println
> ( "-F " + s ) ; } }
> results = line.getOptionValues ( "flob" ) ;
> if ( results != null ) { for ( String s : results ) { System.out.println

> {code}
> when compiled and executed under 1.0 produces:
> trial:
> [java] -F 1
> [java] -F 3
> [java] -F bla
> [java] -F 76
> [java] -F 54
