Hyphen inside an argument with variable arity can't be parsed

[Saulis]

Basically, if you have argument with variable arity and hyphen inside the argument: "-argument1 foo - bar -argument2...", exception is thrown. Works fine if arity would be set to 3 in this case.

package org.saulis;

import com.beust.jcommander.JCommander;
import com.beust.jcommander.Parameter;
import org.junit.Test;

import java.util.List;

public class HyphenTest {

    public class Arguments {

        @Parameter(required = true, names = "-argument1", variableArity = true)
        public List<String> argument1;
    }

    @Test
    public void hyphenIsParsed() {
        Arguments arguments = new Arguments();

        new JCommander(arguments, "-argument1", "foo", "-", "bar");
    }
}

Throws:

com.beust.jcommander.ParameterException: Unknown option: -
