Life at Eclipse

Musings on the Eclipse Foundation, the community and the ecosystem

On Complexity and Good Intentions

We are now about six months into the process of migrating Java EE to the Eclipse Foundation, and I think we’re all learning a lot as we go. I wanted to take a moment and take stock of the scale of this project, its complexity, and where we are.

Java EE is a (roughly) twenty year old technology that is one of the world’s most successful software platforms. It powers the business critical applications that run our modern world. Millions of developers work with Java EE technologies every day. Billions of users use these systems every day. Throughout Java EE’s twenty year history it has been developed and marketed in a pretty particular way.

At the core of Java EE’s success has been an approach that enabled a multi-vendor ecosystem where enterprises had a choice of compatible implementations from a number of companies.

  • Java EE specifications were developed at the Java Community Process, using that JCP process where all intellectual property flowed to the Spec Lead, which was usually Sun (later Oracle). All participants in the specification process are signatories of the Java Specification Participation Agreement, which is a fairly complex legal document.
  • Progress and innovation in Java EE was largely governed by and driven within the constraints of this specification process.
  • Java EE reference implementations were, for the most part, developed by Oracle as part of the Glassfish (and related) project and made available under the CDDL and GPLv2+Classpath Exception licenses. Most of the developers were from Oracle, and the architectural vision and project management roles were performed by them. Contributors to the projects signed the Oracle Contributor Agreement that gave Oracle joint ownership of all contributions.
  • TCKs were developed entirely by Oracle and were highly confidential and tightly controlled. You had to sign an NDA just to get a copy of the TCK agreement if you were interested in getting access to the TCKs. The agreements were pretty dense and complex legal documents.
  • It was called Java EE. It had a logo that looked like a coffee cup. These trademarks were owned by Oracle and tightly controlled.
  • Generally speaking the big enterprises that used the technology were not involved in its evolution. For the most part, the contributors to the specs and implementations were from the Java EE platform vendors.

Together we are changing every single one of those items above. All at once. While retaining the core value of enabling compatible independent implementations in a multi-vendor ecosystem.

This is big and it is complicated.

I honestly believe that no institution other than the Eclipse Foundation could handle this task. We have the people, the skills, the history, and the knowledge of how the Java ecosystem works. The staff at the Eclipse Foundation are highly skilled and community minded professionals. Similarly, the team at Oracle, along with the folks from IBM, Payara, Red Hat, Tomitribe and the EE4J PMC are working hard to move this along. Collectively they are working their butts off to support this transition and to make Jakarta EE the platform and community of choice for the next twenty years.

Overall, I believe we’ve been pretty successful at managing the complexity, and working hard to communicate our progress and plans. We haven’t always been perfect, as case in point this past week where we had a bit of a kerfuffle on our Jakarta community mailing list. Without going into the details, I would say that the root cause of that was poor communication on my part. I didn’t do a good enough job in communicating the plans and dates for selecting the new logo. My bad.

Chris Anisczcyk, a good friend and open source community colleague of mine tweeted some months back that “Open source would be a lot more fun if everyone assumed good intentions.” With his wise words in mind, I want to say is this: what we are collectively undertaking here is a massive and complex task. Mistakes and miscommunications are going to happen. But let’s all assume good intentions, and build a community based on trust, honesty, and respect.

And the Name Is…

We are happy to announce that the new name for the technology formerly known as Java EE is….[insert drumroll]… Jakarta EE.

Almost 7,000 people voted in our community poll, and over 64% voted in favour of Jakarta EE. Thanks to everyone who voted, blogged, or tweeted! This has been quite the process, and we are all really happy with the community support throughout.

naming_poll_results

As we have been making progress on migrating Java EE to the Eclipse Foundation there have been a lot of moving pieces and parallel threads, especially around naming. Thankfully, we think we are getting to the end of this, and the names at least are starting to sort themselves out.  We have prepared this handy table to assist with the translation from the old names to the new names.

Eclipse Jakarta Working Group

Old Name New Name
Java EE Jakarta EE
Glassfish Eclipse Glassfish
Java Community Process (JCP) [*] Jakarta EE Working Group (Jakarta EE)
Oracle development management Eclipse Enterprise for Java (EE4J)
Project Management Committee (PMC)

Note that permission for products to formally use the Jakarta EE trademark will be dependent upon passing a as-yet-to-be-defined compatibility program run by EE.next. However, as of today, it is preferred that when you are generically referring to this open source software platform that you call it Jakarta EE rather than EE4J. EE4J, the Eclipse Top-level project,  is the only name we’ve had for a couple of months, but as we at least tried to make clear, that was never intended to be the brand name.

Update: Fixed a typo plus the formatting of the Glassfish row in the translation table.
Update 2: [*] To be clear, the Java Community Process will continue to exist and to support the Java SE and ME communities. However, it will not be the place where Jakarta EE specifications will be developed.
Update 3: Corrected the name of the working group from EE.next to Jakarta EE.

Introducing the EE.next Working Group

As part of our continuing adventures in migrating Java EE to the Eclipse Foundation I am pleased to announce that the draft of the EE.next Working Group charter  has now been posted for community review. Comments and feedback are welcomed on the ee4j-community@eclipse.org mail list. But please please pretty please make sure you read the FAQ (also copied below) before you do.

You can think of this EE.next group as the replacement for the Java Community Process for Java EE. It will be the body that the ecosystem can join and participate in at a corporate level. Individuals can also join if they are committers on EE4J projects. EE.next will also be the place where the new specification process will be created and managed, and where specs will be reviewed and approved.

Under the process for establishing Eclipse Foundation working groups, there will now be a community review period lasting a minimum of 30 days.

 

FAQ

What is the purpose of a working group?

An Eclipse Foundation working group is a special-purpose consortia of Eclipse Members interested in supporting a technology domain. They are intended to complement the activities of a collection of Eclipse Foundation open source projects. Open source projects are excellent for many things, but they typically do not do a great job with activities such as marketing, branding, specification and compliance processes, and the like.

What is the role of the PMC versus the working group or the working group Steering Committee?

Eclipse Foundation projects are self-governing meritocracies that set their own technical agendas and plans. The Project Management Committee for an Eclipse top-level project oversees the day-to-day activities of its projects through activities such as reviewing and approving plans, accepting new projects, approving releases, managing committer elections, and the like.

Working groups and their steering committees are intended to complement the work happening in the open source projects with activities that lead to greater adoption, market presence, and momentum. Specifically the role of the working group is to foster the creation and growth of the ecosystem that surrounds the projects.

Working groups do not direct the activities of the projects or their PMC. They are intended to be peer organizations that work in close collaboration with one another.

Who defines and manages technical direction?

The projects manage their technical direction. The PMC may elect to coordinate the activities of multiple projects to facilitate the release of software platforms, for example.

Because the creation of roadmaps and long term release plans can require market analysis, requirements gathering, and resource commitments from member companies, the working group may sponsor complementary activities to generate these plans. However, ultimately it is up to the projects to agree to implement these plans or roadmaps. The best way for a working group to influence the direction of the open source projects is to ensure that they have adequate resources. This can take the form of developer contributions, or under the Member Funded Initiatives programs, working groups can pool funds to contract developers to implement the features they desire.

Why are there so many levels of membership?

Because the Java EE ecosystem is a big place, and we want to ensure that there are roles for all of the players in it. We see the roles of the various member classes to roughly align as follows:

  • Strategic members are the vendors that deliver Java EE implementations. As such they are typically putting in the largest number of contributors, and are leading many of the projects.
  • Influencer members are the large enterprises that rely upon Java EE today for their mission critical application infrastructure, and who are looking to EE.next to deliver the next generation of cloud native Java. They have made strategic investments in this technology, have a massive skills investment in their developers, and want to protect these investments as well as influence the future of this technology.
  • Participant members are the companies that offer complementary products and services within the Java EE ecosystem. Examples include ISVs which build products on Java EE, or system integrators that use these technologies in delivering solutions to their customers.
  • Committer members are comprised of the committers working on the various EE4J projects who are also members of the Eclipse Foundation. While the Eclipse bylaws define the criteria for committers to be considered members, in essence any committer members are either a) a committer who is an employee of an EE.next member company or b) any other committer who has explicitly chosen to join as a member. Giving Committer members a role in the working group governance process mimics the governance structure of the Eclipse Foundation itself, where giving committers an explicit voice has been invaluable.

What makes this different from the Java Community Process (JCP)?

The EE.next working group will be the successor organization to the JCP for the family of technologies formerly known as Java EE. It has several features that make it a worthy successor to the JCP:

  1. It is vendor neutral. The JCP was owned and operated first by Sun and later by Oracle. EE.next is designed to be inclusive and diverse, with no organization having any special roles or rights.
  2. It has open intellectual property flows. At the JCP, all IP flowed to the Spec Lead, which was typically Oracle. We are still working out the exact details, but the IP rights with EE.next and EE4J will certainly not be controlled by any for-profit entity.
  3. It is more agile. This is an opportunity to define a 21st century workflow for creating rapidly evolving Java-based technologies. We will be merging the best practices from open source with what we have learned from over 15 years of JCP experience.

Is the WG steering committee roughly equivalent to the JCP Executive Committee?

No, not really. The JCP EC always had two mixed roles: as a technical body overseeing the specification process, and as an ecosystem governance body promoting Java ME, SE, and EE. In EE.next the Steering Committee will be the overall ecosystem governance body. The EE.next Specification Committee will focus solely on the development and smooth operation of the technical specification process.

Does a project have to be approved as a spec before it can start?

That is actually a decision which will be made by the EE4J PMC, not the working group. However, it is a goal of the people and organizations working on creating this working group that the Java EE community move to more of a code-first culture. We anticipate and hope that the EE4J PMC will embrace the incubation of technologies under its banner. Once a technology has been successfully implemented and adopted by at least some in the industry, it can then propose that a specification be created for it.

In addition to the Steering Committee, what other committees exist?

There are four committees comprising the EE.next governance structure – the Steering Committee, the Specification Committee, the Marketing and Brand Committee, and the Enterprise Requirements Committee. A summary of the make-up of each of the committees is in the table below.

Strategic Member Influencer Member Participant Member Committer Member
Member of the Steering Committee Appointed Elected Elected Elected
Member of the Specification Committee Appointed Elected Elected Elected
Member of the Marketing Committee Appointed Elected Elected Elected
Member of the Enterprise Requirements Committee Appointed Appointed N/A N/A

EE4J: Current Status and What’s Next

There is a lot going on as Java EE continues its migration to the Eclipse Foundation. Since there are so many parallel threads, I thought it would be a good idea to recap where we are, and what is coming up in the next few weeks.

First off, we are continuing to work on arriving at a new brand name. Last week the PMC provided the Eclipse Foundation with a potential list of names, and we are running trademark reviews to see if we believe that they can be properly secured. Obviously, we need to have a high degree of confidence that we can freely use the name around the world if we are going to use it to replace some as well known as Java EE. Once we have a short list of potentials we will be starting a community vote to help arrive at a final choice.

Secondly, the code is moving from the existing Oracle-led Java EE organization on GitHub into EE4J. The first nine projects which were proposed have all been created and provisioned, and the code is being moved into them as we speak. The next step on this front will be to propose the next round of projects to move next. As I understand it, the Oracle team will be proposing the JSON-B API and JavaMail projects next. Soon after will come JAX-B, JAX-WS, JSTL, UEL, JAF, Security, JTA, Enterprise Management, Concurrency, and Common Annotations. Everyone involved strongly believes that a key factor in the success of this entire migration is the rapid creation of a diverse and engaged open source community around this code, so we are moving as rapidly as possible to get these projects up and running.

We want to demonstrate to the world that these projects are capable of shipping. Therefore the short-term objective is to have the EE4J project ship a Java EE 8-compliant release as quickly as possible: i.e. a Java EE 8 certified release of Eclipse Glassfish and related projects. There are a couple of positive reasons for doing this:

  1. It demonstrates that the EE4J projects are fully functional as open source projects, and that they and the PMC can run through the full process of a release under the auspices of the Eclipse Foundation and the Eclipse Development Process.
  2. It gets downloadable code that users and adopters can access and run from EE4J as quickly as possible. Creating an ecosystem of developers and companies using this code is important, and the sooner we start the better.

A comment on the API projects that are moving over: several have asked on the mailing lists if the fact that the source has moved means that we can start changing the APIs directly in the EE4J projects. The short answer is “please, not quite yet”. There are several reasons for that:

  1. We want to focus in the short term on shipping an EE 8 compliant release. So the fewer moving parts while we’re doing that, the better.
  2. There is going to be a new spec process that is going to be managing the evolution of these APIs in the future, and it hasn’t been set up yet.
  3. As has been discussed in several venues, this new spec process is going to be bootstrapped with some rules around the continued use of the javax namespace. We’re still working on what those rules are.

In the meantime if you really want to start prototyping some new APIs you are always free to fork the repos on GitHub.

Finally, we are working on establishing an Eclipse Foundation working group to provide a member-driven governance model for the EE4J community. Working groups are consortia which complement the Eclipse open source projects. Community-driven open source projects are great for a lot of things, but don’t do well with business and ecosystem topics such as marketing, developer outreach, branding, specifications, compliance programs, and the like. The first step in creating a working group is to write its core governance charter. We hope to have a draft of that available for review by the end of the month as well. My next blog post will provide some additional information and background on that topic.

Eclipse Community Directions for 2018

As 2018 begins I would like to share a few thoughts on where I think the Eclipse community is heading.  I am looking forward to an incredibly busy year for myself, the staff of the Eclipse Foundation, and our community, because this is going to be a year of tremendous growth and opportunity. I will try to give a brief overview of what I see as some of the exciting things that are going on at the Eclipse Foundation. I am sure that I will miss some, so apologies in advance!

Of course the big news of the past few months was the announcement by Oracle that Java EE is going to be moving to the Eclipse Foundation. This represents the largest single contribution to the Eclipse community since — well, the original Eclipse IDE project in 2001. It is approximately 35 new projects, hundreds of new committers and contributors, and millions of lines of code. It is and was an incredible endorsement of the Eclipse Foundation’s mission as the leading organization for individuals and companies to collaborate on commercial-friendly open source software. Since the announcement in September, we have created the new Eclipse Enterprise for Java (EE4J) top-level project, and source code is starting to move into the projects. During 2018 our collective mission will be to create a functioning and successful community around this code, pick a new brand to replace Java EE going forward, ship a release compatible with Java EE 8, open source the Java EE TCKs, and establish a new specification process to shape the future of cloud native Java. I feel out of breath just thinking of it.

But in addition to this Java EE work, it is clear that the Eclipse Foundation is now playing a pivotal role in the future of the Java ecosystem. Projects such as Eclipse MicroProfile (microservices for Java), Eclipse OpenJ9 (Java virtual machine), Eclipse DeepLearning4J (machine learning), Eclipse Collections (highly scalable collections), Eclipse JNoSQL (NoSQL for Java EE) and Eclipse Vert.x (reactive apps for Java) are leading the next generation of Java innovation.

From the Eclipse Science community comes Eclipse XACC, which I believe is the world’s first community-led open source project in the new field of quantum computing. Originating from Oak Ridge National Laboratory, XACC is working to integrate quantum processors with the high-performance computing environments that are the backbone of modern scientific computing. It will be exciting to see XACC ship its first release in 2018, and to support its desire to create an open collaboration to shape the next generation of computing hardware and programming paradigms.

The Eclipse IoT community has been a significant growth area within the Eclipse community over the past couple of years. In 2017 Eclipse IoT grew to over 25 projects, and is attracting a substantial developer and corporate community.. It is also a terrifically ambitious group, with a vision of providing technology stacks that span the smallest of constrained devices, through device gateways, to cloud-scale data collection and management runtimes. Late in 2017 the group published a white paper on the role that open source will play in Industry 4.0, or industrial IoT. This white paper is important because in many ways it sets out the vision for the group, which has been primarily focused on industrial IoT. In 2018 the primary goal for Eclipse IoT is to start shipping these stacks rather than simply projects. In other words, to create cross-project collaborations that provide IoT adopters with more complete solutions rather than individual building blocks. This will go a long way to paving the way for broad industry adoption of these open source IoT technologies.

Finally, a word on developer tools — the Eclipse Foundation’s original franchise. I noticed recently that according to at least one source, the Eclipse IDE is maintaining its position as the #1 IDE in the world, and grew its market share substantially last year. The goal for this year is to continue this trend. In addition, the Eclipse Che cloud IDE continues to grow its community and adoption. As more and more developers work on cloud native applications, the appeal of a cloud IDE that works where they do is going to grow. Che is well positioned to be the leader in this space and is the only community-led cloud IDE.

Anyone who has seen me speak over the past couple of years has likely heard me express the idea that the “community is the capacity.” The Eclipse Foundation is a 30 person organization that supports a community of hundred of projects, hundreds of members, thousands of committers and contributors, and millions of users. Whenever I take a moment to reflect on what we accomplish together it is breathtaking. The breadth of the technology that we collectively produce is vast, and our community spans the globe. Equally exciting, engagement continues to grow with a variety of industries notably automotive, power, transportation, etc. interested in leveraging the Eclipse Foundation as the place for open, commercial collaboration.

I am incredibly optimistic that 2018 is going to be one of the most exciting years we’ve ever had, so please get involved!

EE4J Code Arrives

Last week the EE4J project achieved an important milestone when the source code for the API and reference implementation of JSON-P JSR-374 project was pushed by Dmitry Kornilov into its GitHub repository in the EE4J organization. This is the first project of the initial nine proposed to reach this stage.

This may seem like a small step in a very large process, but it is a concrete demonstration of the commitment to move forward with the migration of Java EE to the Eclipse Foundation. The Oracle team and the Eclipse Foundation staff had a ton of work to do to make this possible. This is definitely one of those cases where the visible code contributions are just the visible tip of an iceberg’s worth of effort.

Here are just a few examples of the work that went on to get to this stage:

  • The names of the projects such as Glassfish represent important trademarks in the industry. Oracle transferred ownership of these project names to the Eclipse Foundation so that they can be held and protected for the community.
  • The EMO staff reviewed the projects proposals, ran the project creation review, provisioned the repositories and set up the committer lists.
  • The Oracle team packaged up the source code and updated the file headers to reflect the new EPL-2.0 licensing.
  • The EMO IP staff scanned the code and ensured that all was well before approving it for initial check-in.

Now that the collective team has run through this process with JSON-P we will be working to get the remaining eight initial projects pushed out as quickly as possible. Hopefully by the end of this month. Meanwhile, more projects will be proposed and we will be migrating a steady stream of Java EE projects into EE4J.

Exciting times!
