  15. 15. How the JCP works15 May 2011
  16. 16. How we do it • Java Specification Requests (JSRs) – A JSR is a single version of a Java specification. – JSRs are led by a community member (the Spec Lead), with a group of interested members (the Expert Group) helping with the day-to-day decisions and work. – Any community member can submit and lead a JSR. • JSR Deliverables – Each EG must deliver at the end of the JSR lifecycle: • The Specification • The Reference Implementation (RI) • The Technology Compatibility Kit (TCK)16 May 2011
  17. 17. The compatibility triangle • Specification In the specification Can you build an unambiguous? implementation? Technology Reference Compatibility Kit Implementation Is the TCK correct? Does the RI conform?17 May 2011
  18. 18. Deliverables18 May 2011
  19. 19. Compatibility testing19 May 2011
  20. 20. Governance• Java Specification Participation Agreement (JSPA) – A legal contract between members and Oracle. – Addresses Intellectual Property (IP) grants and the terms under which the spec, RI, and TCK should be licensed. – http://www.jcp.org/aboutJava/communityprocess/JSPA2.pdf.• JCP 2: Process Document – Defines the governance of the organization. – Defines the processes that are used to submit define, develop, review, approve, and maintain specifications. – Defines the obligations to produce an RI and TCK, and to define a test challenge process. – http://jcp.org/en/procedures/jcp2.20 May 2011
  21. 21. Organization21 May 2011
  22. 22. Roles • JCP Chair – Leads the organization and manages the PMO. • Program Management Office (PMO) – Manages day-to-day operations of the organization. • Executive Committees – Define JCP governance, processes, and contractual terms of membership. – Vote on JSRs at defined stages through the process. • Expert Groups – Create JSRs (write the spec, develop the RI and TCK). • Members – Review specs, may participate in Expert Groups, vote in Executive Committee elections.22 May 2011
  23. 23. The Executive Committees • Two Executive Committees: – One for Java ME and one for Java SE and Java EE combined. • Each EC has 16 members. • Oracle has a permanent seat on each EC. • 10 of the other 15 seats are ratified by Oracle. – Oracle nominates a candidate; the entire JCP membership approves via ballot. • The remaining 5 seats are elected (any JCP member may nominate themselves.) • Yearly elections reconfirm or replace one-third of the members. • ECs meet ~monthly by phone, 3 times a year face-to-face. • EC meeting minutes are public. – See http://jcp.org/en/resources/EC_summaries.23 May 2011
  24. 24. Executive Committee responsibilities • Review and vote on all JSRs associated with their EC. • Evolve the JSPA and the Process Document. – The JSPA and Process Document are modified through the JSR process itself. – The Executive Committees serve as the Expert Group for JSRs that make these changes; the Chair is the Spec Lead. – JSR 99 defined the JSPA, JSR 215 defined the Process Doc. – Two new JSRs to evolve the JSPA and Process Doc will be filed soon (JCP.next.) • Represent their own interests to the JCP and the JCP to the developer and user community. • Advise the PMO.24 May 2011
  25. 25. Current Executive Committee membership • Java ME EC – Stefano Andreani, Aplix, AT&T, CableLabs, IBM, Nokia, Oracle, RIM, Samsung, Sean Sheedy, Siemens, SK Telecom, T-Mobile, TOTVS, Vodafone. – One vacancy recently filled by a Special Election (Alex Terrazas). • Java SE/EE EC – Credit Suisse, Eclipse, Ericsson, Fujitsu, Google, HP, IBM, Intel, Werner Keil, Oracle, Red Hat, SAP, Vmware. – Three vacancies recently filled by a Special Election (Goldman Sachs, SouJava, London Java Community).25 May 2011
  26. 26. The Spec Lead • The individual or institutional owner and driver of a JSR. – Recruits and organizes the activities of the Expert Group. – Responsible for delivering the Spec, RI, and TCK. • Intellectual Property rights to the technology incorporated in the JSR accrue to the Spec Lead. – Subject to obligations incurred under the JSPA. • The Spec Lead is free to define the terms under which the RI, and TCK will be licensed. – Subject to obligations incurred under the JSPA. • Oracle is the Spec Lead for the three existing Platforms: Java ME, Java SE, and Java EE.26 May 2011
  27. 27. The Expert Group • The Expert Group is recruited and led by the Spec Lead. – All members of the JCP are eligible to join. – Participation by all interested parties is encouraged and desirable. – The EG works as a team to define the JSR and to develop the Spec, RI, and TCK. • The EG is free to define its own working style. – When and how often it meets, how it makes decisions... • Transparency is strongly encouraged. – EGs must explain their transparency strategy: • Public aliases, public issue list, Wikis, blogs... – EGs must respond publicly to comments.27 May 2011
  28. 28. The membership • Anyone can join. • Total membership is approximately 1500. • 3700 registered users at jcp.org (not affliliated with a member). • Fees: – Java Licensees: free. – Individuals: free – Java User Groups: free. – Non-profit organizations: $2K/year. – Commercial organizations: $5K/year.28 May 2011
  29. 29. Who are the members? • Membership distribution by type: – 77% individual. – 21% corporate. – 2% non-profit. • Membership distribution by location: – 50% North America – 32% Europe and the Russian Federation – 13% Asia and the Middle East – 5% South America29 May 2011
  30. 30. The JSR development cycle30 May 2011
  31. 31. JSR Submission• Identify the submitters, the Specification Lead(s), and the initial members of the Expert Group.• Describe the proposed specification and the reasons for developing it.• Identify the target Platform(s).• Estimate the development schedule.• Describe the working model the Expert Group will adopt, and how it will involve the community and the public.• Identify preexisting documents, technology descriptions, or implementations that might be used as a starting point.• Publish the licensing terms for the Spec, RI, and TCK.31 May 2011
  32. 32. JSR Approval Ballot• JSR proposals are published on the JCP website.• JCP members, the Executive Committees, and the public review and comment.• JCP members may request to join the Expert Group during this period.• The Executive Committee(s) vote on the JSR during the final two weeks of the review period.• If the JSR is voted down, submitters have 14 days to revise and resubmit for a second vote; if this fails the JSR is closed.32 May 2011
  33. 33. Expert Group formation• Expert Group formation begins when the JSR is approved.• Members request to join the EG through an online form.• No size limit; Spec Leads should ensure that all interested parties are represented, but should keep the group small enough that it will be able to function efficiently.• Members may be added at any time, subject to the agreement of the existing membership.• EG decides its mode of operation (communication mechanisms, meeting schedules, etc.) – Transparency and community involvement are strongly encouraged.33 May 2011
  34. 34. Early Draft• The Expert Groups first deliverable is the Early Draft. – Provides the JCP membership and the public with a draft that is detailed enough to generate useful feedback.• No fixed deadline for generating the draft – EGs should take as long as they need (but no longer!)• Early Draft is published for review on the JCP website. – Review period is typically 30 days but may be longer.• No ballot at this stage – the purpose is to gather feedback.• EGs may choose to revise the draft and resubmit if feedback indicates that significant changes need to be made. – OK to iterate through several Early Draft reviews.34 May 2011
  35. 35. Public Review• Spec should be relatively complete before Public Review.• Expert Group should also be developing the RI and TCK while working on the spec.• Spec is published for review on the JCP website. – Review period is 30 – 90 days (the EG decides how long).• All public comments should be considered and addressed.• The Public Draft Specification Approval Ballot takes place during the final 7 days of the review• If the ballot fails, the EG has 30 days to resubmit for a Reconsideration Ballot. – If this ballot fails, the JSR is closed.35 May 2011
  36. 36. Proposed Final Draft• The EG submits a Proposed Final Draft of the spec to the PMO. – This should incorporate and address feedback from the Public Review.• Spec is posted on the website for public download.36 May 2011
  37. 37. Final Approval and Release• The EG prepares the Final Draft of the spec and completes the RI and TCK. – The TCK must meet quality and coverage goals. – The RI must pass the TCK. – A test appeals process must be defined. – Final RI and TCK licensing terms must be published.• The EC has two weeks to review these materials and to cast their votes in the Final Approval Ballot.• If the ballot fails the EG has 30 days to resubmit for a Reconsideration Ballot; if that fails, the JSR is closed.• Approved JSRs are posted for Final Release and may then be implemented commercially.37 May 2011
  38. 38. Maintenance• Spec Leads are expected to make a long-term commitment to revise and update the spec, RI, and TCK.• Spec Lead typically takes on the role of Maintenance Lead. – Gathers Proposed changes, deciding which to Accept and which to Defer, publishing these on the JCP website.• 30-day public Maintenance Review period (no ballot unless EC members intervene to request items be deferred).• RI and TCK must be synchronized with spec changes. – Maintenance Release is final when this is completed.• More significant changes (beyond minor clarifications of the spec) require a new JSR.38 May 2011
  39. 39. Summary of JSR Stages• JAB: JSR Approval Ballot - Mandatory - 2 weeks.• EDR: Early Draft Review - Mandatory - 30/45/60/90 days.• PR: Public Review - Mandatory - 30/45/60/90 days.• PRB: Public Review Ballot – Mandatory - 7 days.• PFD: Proposed Final Draft - Mandatory - no time frame.• FAB: Final Approval Ballot - Mandatory - 2 weeks.• FR: Final Release - Mandatory.• MR: Maintenance Review - Optional - 30/45/60/90 days.• MREL: Maintenance Release - Optional. Each stage must be completed before the Expert Group moves on to the next.39 May 2011
  40. 40. Open Source40 May 2011
  41. 41. Open Source processes• Half of all currently-active JSRs are developed as open source projects. – Java SE: OpenJDK. • http://openjdk.java.net/ – Java EE: Project Glassfish. • http://glassfish.java.net/• Most Expert Groups have adopted some aspects of the open-source development process.41 May 2011
