Dear Experts,
After a discussion with Marek, and mainly due to the slowness of the JSR thus far, I’d like to propose that we prioritize on what we consider the main features of the 2.1 release (in hindsight, we may have included too many features for a dot release!):
(1) Reactive API
(2) Non-blocking I/O
(3) SSE
(4) Alignment with MVC and JSON-B
We feel that if we focus on these features, we should be able to produce an EDR before the end of the calendar year, and possibly deliver a complete spec within 9 months; alignment with the other specs will naturally depend on their schedule. Features not on this list would be considered for a future version of JAX-RS, either 2.2 or a 3.0.
It is time that we show some progress to the community and the JCP, and we feel this more focused plan will get us there. We hope you will support us. We have actually done some work over the last weeks around Reactive and NIO that we plan share shortly.
