7. History
•
1995: Sun Microsystems develops Java.
•
1999: Sun opens up the development process to its competitors,
creating the Java Community Process.
•
2006: Sun open-sources Java SE and Java EE.
•
2007: Sun goes into f inancial decline; Java stagnates.
•
2010: Oracle acquires Sun and becomes the steward of Java.
7

8. Oracle infuses energy and funding into
Java and the JCP, resulting in:
• New revisions of each
of the three platforms:
Java SE, Java ME,
Java EE
• “JCP.Next” reforms to
improve the way the
Process operates
• Increased participation
and new initiatives
from Java User Groups
2011 - Present Day
8

9. Oracle as Java’s Steward
•
Oracle recognizes the great value of Java – to itself as well as to its
allies and competitors.
•
The value is derived from the open, collaborative, standards-based
process through which Java is developed and the vibrant developer
community that this process fosters.
– A proprietary platform could not have succeeded as Java has
– Java is everywhere
•
Oracle’s support and promotion of Java benef its everyone.

11. Background
11

12. The Java Community Process
•
Java specif ications (JSRs) are developed collaboratively through an
open, formal process similar to that used by other SDOs. All
interested members of the Java Community may participate.
•
Oracle’s competitors are active participants.
– IBM, HP, and RedHat to name a few.
•
The Open Source and developer communities are also represented.
– The Eclipse Foundation, Java User Groups.

Freescale Fujitsu Gemalto M2M
Goldman Sachs HP IBM
Intel Werner Keil London Java Community
Geir Magnusson MicroDoc Oracle
Red Hat SAP Software AG
SouJava TOTVS Twitter

14. 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

18. Java SE 8: JSR 337 (March 2014)
18

19. Java ME 8: (JSRs 360 & 361) – April 2014
19

20. Java EE 7: (JSR 342) – May 2013
20

21. How do we do it?
•
Java Specif ication Requests (JSRs).
– A JSR is a single version of a Java specif ication.
•
JSRs are led by a JCP 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 Specif ication.
– A Reference Implementation (RI).
– A conformance test suite (Technology Compatibility Kit, or TCK).
21

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

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

24. Organization

organization.
•
Executive Committee

•
Members
– Review specs, may participate in Expert Groups, vote in EC elections.
25

26. Executive Committee
•
The Executive Committee has 25 members – vote on JSRs, def ine
JCP program governance.
•
Oracle has a permanent seat.
•
16 seats are Ratif ied (Oracle nominates candidates and the entire
JCP membership must approve them by voting).
•
The remaining 8 seats are Elected (any JCP member may nominate
themselves and members choose by voting).
•
Each year half of the members must stand for re-election.

33. JCP.next: Changing the Constitution

34. Legal Framework and Governance
•
The Java Specif ication Participation Agreement (JSPA)
– A legal contract between members and Oracle.
– http://www.jcp.org/aboutJava/communityprocess/JSPA2.pdf.
•
The Process Document
– Def ines the governance of the organization.
– http://jcp.org/en/procedures/jcp2.
34

35. Using the Process to Change the Process
●
We modify the Process (as def ined in the JSPA and the Process
Document) by f iling JSRs.
●
The Chair&/or the PMO is the Spec Lead and the Executive
Committee members form the Expert Group for these JSRs.
●
Since 2011 we have been working on a series of four JSRs,
collectively referred to as JCP.next, to reform the our processes.
35

36. JCP.next.1 (JSR 348)
36

37. JCP.next.2 (JSR 355)
37

38. JCP.next.3 (JSR 358)
●
The JSPA has not been signif icantly modif ied since 2002.
●
Since then the organization and the environment in which we
operate have changed signif icantly.
●
This JSR will modify the JSPA and the Process Document,
def ining new (and hopefully simpler) IPR and licensing policies.
38

39. JCP.next.4 (JSR 364)
●
This JSR was spun-off from JSR 358 in order to implement
membership-related changes more quickly.
– Should be f inal in June 2015.
●
Goal: Broadening JCP Participation.
– Encourage more individuals to join and participate in the JCP
while ensuring that we have appropriate IP commitments.
– New Associate membership class for individuals.
●
New Partner membership class for Java User Groups.
●
Free membership for corporations.
39

40. The JCP is more open than before
•
Public JSR schedule--current, and updated regularly.
•
Public read and/or write page/wiki for the JSR.
•
Public discussion for the work of the JSR (archived).
•
Public feedback mechanism.
•
Public issue tracker.
•
One EC votes on all JSRs 3x in life of JSR with public results.
•
All JSRs have 3 open public review periods (30 days).
– Release early and often!
40

41. How will you Participate?
•
As an Individual – OK.
•
As part of a team – better.
•
Work through your JUG or
employer.
– Help each other
– Teach other.
– Work with each other.

42. Adopt-a-JSR
● A JUG-lead initiative to
improve Java standards.
● Groups of JUG members
work on JSRs.

45. How to get started - easy
●
Comment on the mailing lists; steer towards helpful conversations
●
Evangelize the JSR through social media, blogging or lightning talks.
●
Give a talk at your user group at events, or online.
●
Help with documentation.
●
Translate into your native language.
●
Help to maintain an FAQ/Wiki.
●
Improve project & JSR visibility.
●
Comment on the drafts and issue trackers.
●
Ensure that downloads, mailing lists, issue trackers are easy to f ind.
45

46. How to get started - moderate
●
Organize Hack days.
●
Test the early RI builds; use them to f ind 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.
●
Help build the TCK; all implementations must pass the test suite – this
is a great way to gain test experience.
