Java Community Process

The Java Community Process (JCP), established in 1998, is a formalized mechanism that allows interested parties to develop standard technical specifications for Java technology. Anyone can become a JCP Member by filling a form available at the JCP website. JCP membership for organizations and commercial entities requires annual fees – but is free for individuals.[1]

The JCP involves the use of Java Specification Requests (JSRs) – the formal documents that describe proposed specifications and technologies for adding to the Java platform. Formal public reviews of JSRs take place before a JSR becomes final and the JCP Executive Committee votes on it. A final JSR provides a reference implementation that is a free implementation of the technology in source code form and a Technology Compatibility Kit to verify the API specification.

A JSR describes the JCP itself. As of 2009, JSR 215 describes the current version (2.7) of the JCP.

The JCP's executive board has been characterized ***** as a "rubber stamp organization" since Oracle acquired Sun Microsystems (the original developer of the Java language).[10] The Apache Software Foundation resigned its seat on the board in December 2010 because Oracle was unwilling to license the Technology Compatibility Kit for Apache's version of Java.[11]
