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.
The JCP itself is described by a JSR. As of 2020, JSR 387 describes the current version (2.11) of the JCP.

Criticism
A JCP representative (far right) speaks to the trade press during a panel discussion at the JavaOne conference in 2012
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]
