Virtual Hackday: Become an early Java 9 expert


This was a joint hackday broadcast between the Virtual JUG and the Atlanta JUG, live from Atlanta.

You can take part in Java technology evolution through the Java Community Process (JCP) program. You can participate in this session on your own as an individual, through your employer, or as part of a nonprofit such as a Java User Group (JUG). Currently, there are JSRs being finalized for the Java EE 8 and Java SE 9 platforms.

In this session, we will be doing a hackday as part of the global Adopt OpenJDK program getting ready for the release of Java SE 9. We kicked off a testing program in 2016 and now it is really the time to be getting ready the release of Java 9 coming in September 2017. This is a hack day as part of the ongoing global adoption and outreach effort.

We held be holding an all-day hands-on hack session covering the new modules system in Java 9, the JLink tool which allows you to create Java images with your application, and also how to migrate to the new Java 9 modular system with an older application. A laptop is required. Bring your project and run it on Java 9 EA with fellow JUG members!

Setup and verify your system by going through these steps:
