Demonstrates the features that will be available in Java 9. The links below take you to the demo in this project, the JEP responsible for introducing the feature, and to other sources if available.
This article list a lot of the upcoming changes:
- The Ultimate Guide to Java 9
- Inside Java 9 – Version Schema, Multi-Release JARs, and More
- Inside Java 9 – Performance, Compiler, and More
Putting everything here will take a while, so you have to be patient. If you can't, check out the JDK 9 page and look through the JEPs. You can read more from me on codefx.org and follow me on Twitter (and even G+, I guess).
The scripts are written for Linux but should look similar on other operating systems. They do need three symlinks, though:

The module system is too big to demo here. Check out the jigsaw and jpms tags on my blog or this demo project.
