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.

OpenJDK is now a well established Free Software Ecosystem, with a vibrant Community and lots of interesting stuff going on, with projects, repositories, bug database and above all experiments!

This is exciting and fun, but given the challenges of such massive project, it is intimidating and it is easy to get lost. It is also easy to forget that such massive infrastructure requires well defined rules, that are sometime perceived as blocking rather than aiding the participation. To help people wanting to contribute keep track of this intricate forest of development and find their way in, the Adoption Group was created (http://openjdk.java.net/groups/adoption/).

This session is an exchange between few of the hackers directly involved with the Adoption Group and the public, we will answer questions the audience may have in relation to getting involved with OpenJDK, try to define and explain workarounds for most common problems (and blockers!) that newcomers face, discuss some of the projects we are currently involved with, and hope to be your Ariadne's thread to win back the fun of contributing and participating at all levels, without ever getting lost!

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.

There's a ton of stuff going on in OpenJDK, projects, repositories, bug database, experiments. This is a lot of potential fun, but the entrance barrier for newcomers is extremely high, and it's easy to get lost and not enjoy the fun anymore. In order to help people wanting to contribute keep track of this intricate forest of development and find their way out, the Adoption Group was created (http://openjdk.java.net/groups/adoption/).

This session is an exchange between few of the hackers directly involved with the Adoption Group and the public. We will indeed discuss some of the projects we are currently involved with - like the planned global hack days for jsonp, jigsaw and tools that use jigsaw and http 2.0 with language interoperability - but above all we will answer questions the audience may have in relation to getting involved with OpenJDK, both from a technical perspective and a social one, so that next year you can sit together with us helping even more people to jump on the fun!

If you need help organising your next hackday, or you are completelylost tying to get started with OpenJDK, this is the session for you!

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.

The JDK 7 Updates Project in the OpenJDK Community has been around for more then two years, breaking a new ground in how JDK updates are made and trying out a few new things in the process. This session will go into lessons learned from producing updates to the JDK as part of an Open Source project.

The JDK 7 Updates Project in the OpenJDK Community has been around for more then two years, breaking a new ground in how JDK updates are made and trying out a few new things in the process.

This session will go into lessons learned from producing updates to the JDK as part of an open source Project. Some of the new things worked, while others required some tweaking. I'll cover lessons learned on a broad set of technical issues, from forest and repository management, tagging, development processes & transparency to release management and communication.

This talk goes into the details of what is already present in the OpenJDK source code repositories of both the Nashorn and OpenJFX Projects.

As part of the presentation, you will learn how to build, run and test each of the Projects, and how to do something fun with them both.

In this talk you'll learn how the JDK 7 Updates Project in OpenJDK works, and how to work within it, how to track changes, get your fixes in, and follow along as for example the Mac OS X Port gets integrated into future JDK 7 update releases.
