The document summarizes the Java Community Process (JCP) and its role in the future of Java. It discusses how the JCP facilitates collaborative development of Java specifications through Java Specification Requests (JSRs). It also outlines recent JSRs and releases, as well as planned improvements to the JCP through increased transparency, membership changes, and other reforms. The presentation encourages participation in the JCP to help shape Java's future.

13. 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)
•.
13

14. Compatibility Triangle
Can you build an
implementation?
Is the specification
unambiguous?
Is the TCK correct?
Does the RI conform?
14

15. 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.
