The document discusses the Java Community Process (JCP) and the future of Java. It provides an overview of the JCP, including its goals of open standards, compatibility, and broad community involvement. It outlines several recent and upcoming Java specifications being developed through the JCP, and encourages developers to get involved in JSR expert groups, hackathons, and other community events to help shape the future of Java.

❑ Open Source Fan
❑ Native Californian - from San Diego
❑ Personal Interests: Fun
Bay Area, California - USA

5. Continued growth
❑ #1 Development Platform, Now in the Cloud
❑ 10 Million Java Developers Worldwide
❑ #1 Choice For Developers
❑ 13 Billion Devices Run Java
❑ 200 Million Medical Devices Run Java
❑ 1 Billion Automotive Devices Run Java
❑ 97% of Enterprise Desktops Run Java

6. Java Philosophies
❑ Platform Completeness
❑ Quality and Security
❑ Modernization and Innovation
❑ Open and Transparent Evolution
❑ Developer Productivity &
Compatibility
❑ Active Ecosystem Involvement

8. Technology Demand
Industry trends indicate that by 2020,
there will be 1.4 million computing jobs
available.
On the surface this sounds great, but

9. ❑ A shift from the one with the
best technical skills wins
❑ To…the one with the best
people skills wins
First Computer Programmer

10. In 2017… 50% of tech jobs = Technical skills
❑ Top five key soft skills that engineers and other professionals
should develop for career success:
❑ Communication
❑ Creativity/Critical Thinking
❑ Adaptability/Flexibility
❑ Collaboration/Teamwork
❑ Leadership

11. ❑ Not easy to acquire
❑ Require practice
❑ Human interactions
❑ Complex thinker,
relationships, emotional
intelligence = practice with
others
In-demand skills

12. How to acquire?
❑ Engage in Community events
❑ User Group Meetings
❑ Conferences
❑ Open Source Projects
❑ Java Community Process (JCP)
❑ Hack days &/or Hackergartens
❑ Kids coding workshops

14. Why Should Developers Participate?
❑ Knowledge
❑ Skills
❑ Visibility
❑ Altruism
❑ Advance Career
❑ Fun

15. Membership Quotes
❑ "Joining the JCP, especially being a member of several expert
groups, has had a big impact on my career. Mostly by making it
visible for the leadership and managers in my company that I am
actually a part of forming the future of the platform. I also think,
or hope, that it is an inspiration for my colleagues."
- Ivar Grimstad
❑ "Joining the JCP is like being a Java citizen."
- Heinz Kabutz

16. Collaborative Development - How does is work?
❑ 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)
•.

17. The JSR Development Cycle
❑ Includes formal public reviews and votes by the Executive
Committee.
❑ Full Members can submit & lead JSRs, serve on JSR Expert
Groups.
❑ See the Process Document for the details.

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

24. How: Open Standards & Open Source
❑ We need both!

25. Complimentary
❑ Open source important requirement. So are Standards.
❑ Coop-etition. Agree on what to standardize (cooperation) & what
to compete 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.

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

27. ❑ New revisions of each
of the three platforms.
❑ “JCP.Next” reforms .
❑ Increased participation
from Community.
