How to acquire?

• Java Specification Requests (JSRs)
– A JSR is a single version of a Java specification.
• JSRs are led by a community member (the Spec Lead), with a group of interested
members (the Expert Group) helping with the day-to-day decisions and work.
– Any JCP member can submit and lead a JSR.
• Each Expert Group must deliver:
– The Specification
– A Reference Implementation (RI)
– A Technology Compatibility Kit (TCK)
Collaborative Development - How does is work?

• Includes formal public reviews and votes by the Executive
Committee.
• Full Members can submit & lead JSRs, serve on JSR Expert Groups.
