It now plays the samerole for JDK 9. With a number of large changes being planned for JDK 9 that are being developed through the OpenJDK community, reaching out to popular FOSSprojects well ahead of a release and keeping them informed of upcomingchanges, collecting as well as acting on their feedback created a greatfeedback loop. Today, around 80 open source projects and communities participate in testing of early access builds of the JDK, reporting issues they find, andhelping get them resolved in time. In this session, we'll look at someexamples of how they have helped make JDK 9 better, and discuss how we cantogether improve the OpenJDK Quality Outreach effort for JDK 10.
