public class CliTest extends TestCase {
        CommandLineParser parser;
        
        public CliTest(String name) {
                super(name);
        }
        protected void setUp() throws Exception {
                parser = new PosixParser();
        }
        public void testParamNamedAsOption() throws Exception {
                final String[] CLI_ARGS = new String[] {"-z", "c"};
                Option option = new Option("z", "timezone", true, 
                        "affected option");
                Options cliOptions = new Options();
                cliOptions.addOption(option);
                parser.parse(cliOptions, CLI_ARGS);
                
                //now add conflicting option
                cliOptions.addOption("c", "conflict", true, "conflict option");
                parser.parse(cliOptions, CLI_ARGS);
        }
