MissingArgumentException: no argument for <option> is thrown when the option's

//this will throw exception
$app -l m

import org.apache.commons.cli.*;

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);
	}
}
