In time we hope that jlink will be able to create a static image where everything is in the single executable, so no bin directory (or any directory) for launchers. I don't object to doing something to help testing the intermediate step, just not sure that main line is the right place for this.

Hi @magicus I looked at your changes and focused on the launcher changes. I only looked quickly of the build changes, I think @erikj79's review is sufficient. For launcher changes, my main question is Windows platform support (for static JDK) and testing. The rest of the comments are minor.
