@Optional or @Default not working correctly together @Flag

[bivashy]

When we are defining @Optional and @Flag at the same time, value of parameter will be <?null> Example command:

@Command("test")
public class TestCommand {
    @DefaultFor("test")
    public void onDefault(String first, @Flag("second") @Optional String second) {
        System.out.println(first);
        System.out.println(second);
    }
}

When we execute /test 1 It`ll print out:

1
<?null>

(Second value is plain String)
