Hi Jason/Tomaz, Early-access builds of JDK 9 with Project Jigsaw are available for download at jdk9.java.net/jigsaw <http://jdk9.java.net/jigsaw>;. The EA builds contain the latest prototype implementation of JSR 376 <http://openjdk.java.net/projects/jigsaw/spec>;, the Java Platform Module System, as well as that of the JDK-specific APIs and tools described in JEP 261 <http://openjdk.java.net/jeps/261>;. If you'd like to try out the EA builds, by far the most helpful things you can do are: * Try to run existing applications, without change, on these builds to see whether the module system, or the modularization of the platform, breaks your code or identifies code that depends upon JDK-internal APIs or other unspecified aspects of the platform. * Experiment with the module system itself, perhaps by following the quick start guide <http://openjdk.java.net/projects/jigsaw/quick-start>;, and start thinking about how to migrate existing libraries and application components to modules. We hope to publish some specific migration tips shortly. Please send usage questions and experience reports to the jigsaw-dev <http://mail.openjdk.java.net/mailman/listinfo/jigsaw-dev> list. Specific suggestions about the design of the module system should be sent to the JSR 376 Expert Group's comments list <mailto:jpms-spec-comments@openjdk.java.net>.
