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 technology
compatibility 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.

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

25. @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.
