According to the What's new in Oracle JDK 9 page, No. This has not changed in Java 9.

Of course, that is not definitive, but the JLS for Java 9 has not been released yet.

If you use busser-serverspec, you just write the tests as per normal locally, usually using Net::HTTP.get('http://localhost:8080/whatever').

If you use kitchen-inspec, you need to be a little more roundabout and use something like describe command('curl http://localhost:8080/whatever') and work with it like a normal command resource.

When you run a knife cookbook site download you tell knife to download a .tar.gz of the cookbook in the current directory where you are invoking it. In this case it works for you.

However a knife cookbook site install works differently. It assumes you have your knife.rb value cookbook_path pointing out to a directory in your filesystem which is a chef (and git) repo with (at least) one commit done. Which is not your case as far as I can see in what you're writing here.

You are invoking knife in D:/tools/chef-setupDevEnv/SomeDirectory while your knife.rb tells knife to go #{current_dir}/../chef-java_se which is D:/tools/chef-setupDevEnv/chef-java_se, which probably does not exist and if so, it is not a chef/git repo satisfying the condition I stated in the previous paragraph.

The main usage of install versus download is to have control with branches of changes in the cookbooks you use, you will find more information about its advantages here.
