The Java Community Process (JCP) is key to the evolution of Java technology. This session emphasizes the value of transparency and participation in the JCP program, through both Java User Groups (JUGs), and through the Adopt-a-JSR program, the grass roots, community led and developed program to empower Java developers around the world to make a contribution to Java technology. Find out how to become an active participant in advancing the Java platform - JSRs for Java Enterprise Edition (Java EE) 8 and Java Standard Edition (Java SE) 9 are being developed now. This session discusses the transparency that enables participation in the JCP program and how to get involved through the Adopt-a-JSR program. You will also hear about some upcoming changes to the Java Specification Request (JSR) process itself through the JCP.next effort, and learn how you can get involved. Come with your questions/suggestions, and leave with the motivation and information you need in order to become an active participant in advancing the Java platform now and in the future.

21. Work of the JCP – 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 JCP member can submit and lead a JSR.
• Each Expert Group must deliver:
• The Specification
• A Reference Implementation (RI)
• A Technology Compatibility Kit (TCK)
•. 2

22. Compatibility Triangle
Can you build an
implementation?
Is the specification
unambiguous?
Is the TCK correct?
Does the RI conform?
2

23. The JSR Development Cycle
•Includes formal public reviews and votes by the Executive Committee.
•See the Process Document for the details.

24. How: Open Standards & Open Source
2

25. Complimentary
•Open source important requirement. So are Standards.
• Coop-etition. Agree on what to standardize (cooperation) & what to
complete on (implementations).
•Open standards implemented in open source = easier to
implement standard & for developers to understand technology.
• Results in more implementations and greater adoption of the standard.
•An effective way to develop a standard-start with an open source
project that has demonstrated the need for standardization.
•. 2

26. Open Source Implementations
•The Reference Implementations of the Java SE and Java EE platforms are
also developed collaboratively and released under open-source licenses.
–Java SE: OpenJDK
–Java EE: Project GlassFish

53. Java EE JSRs
3) Decide on Steps: Java EE Adopt-a-JSR

54. ●Test the early RI builds; use them to find pain points, report bugs,
suggest feature enhancements.
●Help triage issues; reproduce issues, erase/merge duplicates, set
priorities/categories etc.
●Give feedback on design; discuss issues and deliver feedback,
think about how you would use the JSR as a developer.
●Help build the RI; get coding with the actual implementation of
the spec or build sample applications.
