This is not nice.
Especially, if you're fun of lambdas. 😉

    public static String join(List<String> list, String delimiter) {
        StringBuilder out = new StringBuilder();
        if (list != null && !list.isEmpty()) {
            out.append(list.get(0));
            list.subList(1, list.size()).stream().forEach((item) -> {
                out.append(delimiter).append(item);
            });
        }

        return out.toString();
    }

BTW, @renner suggests to have at least have a documentation for the whole class with the URL link to it. Maybe Johannes will write more here.

I will open a separate issue to track the documentation of the modules where we also can discuss what to do. In any case adding documentation should be done in a separate PR that covers all modules.

[renner]

Thanks for opening the issue, @lucidd! From my perspective there is no need to add javadoc for the Match module class within this patch, especially I wouldn't want to copy it from the salt documentation for the reasons mentioned in #117. For now let's just do it as the other module classes we already have, i.e. keep it as it is.

While this change makes sense it does not actually seem to belong to this patch.

Oops seems like a left over from a previous version i will remove it. (or rather add it back 😄 )
