How does an expert group get picked?
The JSR submitter (Specification Lead) has responsibility for the formation of the Expert Group, including selection of the experts for the Expert Group. Ideally, the Expert Group should be large enough and diverse enough to insure wide adoption of the resulting specification. Any representative of a JCP Member can nominate themselves to serve on one of the Expert Groups that write Java specifications. Individuals not affiliated with a member can also nominate themselves to serve on an Expert Group. The PMO forwards nominations received using the JSR web page to the Spec Lead, with an indication of whether the nominee is a member. In order to insure that all experts have agreed to the same terms for the sharing of intellectual property, and other terms of Expert Group participation, only JCP Members can join Expert Groups.
