For the community, by the community

• The Java Community Process (JCP) is the open, inclusive

process to develop and revise Java technology specifications

(JSRs), reference implementations (RI), and technologycompatibility kits (TCK).

– The JCP program now has over 800 corporate, individual

and Java User Group (JUG) members.

– More than 370 Java technology specifications are in

development in the JCP program; ~two thirds have

reached Final Release.

• Members.

• Expert Group members.

• Specification Leads.

• Executive Committee members.

Adopt-a-JSR – Community Driven!

• Share ideas and feedback, possibly by entering issues in public

issue trackers.

• Follow expert group discussions.

• Read early versions of specifications and Javadocs.

Participation in the JCP

Joined the JCP in 2013 Interest arised from Java ME 8 JSRs Started JSR 363 – Units of Measurement, to represent units and

measurements. Ratified for the Executive Committee since 2013

@leomrlima

How can YOU make JSR-363 work? It’s an active JSR: YOU can get involved. We are participating in the Adopt-a-JSR program - 3 JUGs have so far joined the EG! (Morocco JUG, SouJava, JUG Chennai). You can download the code, file JIRA Issues for bugs or needs and follow the discussion in our mailing lists. We’re always looking for new ideas and use cases.
