Fellow Experts,
I'm glad to inform you that JAX-RS 2.0 has formally switched to latest JCP 2.9 (
http://jcp.org/en/procedures/jcp2_9). The only change in this version of JCP is introduction of the merged EC, which already voted on JSR 339 PR, so practically we've been already operating under JCP 2.9 since November.
Kind regards,
Marek
