Over the last couple of years, the OpenJDK Quality Outreach effort has become a good source of high quality feedback from many popular FOSS projects starting with JDK 7 Updates, JDK 8 and JDK 8 Updates. It now plays the same role 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 FOSS projects well ahead of a release and keeping them informed of upcoming changes, collecting as well as acting on their feedback created a great feedback loop.

  Today, around 80 open source projects and communities participate

in testing of early access builds of the JDK, reporting issues they find, and helping get them resolved in time. In this session, we'll look at some examples of how they have helped make JDK 9 better, and discuss how we can together improve the OpenJDK Quality Outreach effort for JDK 10.

With JDK 9 development underway in the OpenJDK Community, and based on our experiences with open source projects testing against JDK 9 Early Access builds in the Quality Outreach effort, it seems like a good idea to compile the accumulated wisdom to make it easier for new projects to start testing against JDK 9. In this session, you'll learn how to prepare your code for some of the upcoming changes in JDK 9 and how to join the OpenJDK crowd testing fun with your own open source project to help make JDK 9 better.

In the beginning, there were bugs. In order to find them faster, before a JDK release, the OpenJDK Adoption Group began a quality outreach effort. Initially focused on JDK 8, the effort expanded to cover JDK 7 Updates, JDK 8 Updates and JDK 9 OpenJDK Projects. It now lists dozens of open source projects and communities that participate in testing early access builds of the JDK, report issues they find, and help get them resolved in time.

In this session, you'll learn what worked, and what didn't, and what you can do to join the OpenJDK crowd testing fun with your own open source project to help us find showstopper bugs before they can bite.
