No, that's not the intent. A Java EE 7 product that implements JAX-RS 2.1 will need to run on SE 8. As stated in an earlier message, there are EE 7 products that are already certified to run on SE 8.

Right, is a new spec that starts with EE 8.

I interpret "based on Java SE 8" to mean "we are free to use any SE 8 features, and if we do, you won't be able to run it on SE 7". So this is just like JAX-RS 2.1.
> As Sergey also hinted, that is a two-headed sword. You might get the "goodies" of SE 8 like Lambdas, etc. but keep in mind, an API that relies on SE 8 cannot be implemented by anything under EE 7 with an SE 7 JVM. Nor will the RI or any implementation of that API work with an older Java version.
Right. In those cases, you still have JAX-RS 2.0 implementations available.
> Any new JSR will have to ask itself if it wants to be compatible with at least a large percentage of Java 6 or 7 users, or immediately throw them into the Java SE 8 "pond" for the API.
We need to think down the road. By the time EE 8 is finished, unless plans change, it is possible for the latest SE 7 update release (from Oracle) to be nearly 2 years old. In contrast, I think the latest SE 6 came out in late 2012 or early 2013, much closer to EE 7.

> After collecting the feedback on this alias as well as that of the community (via the survey), we are ready to move forward with JAX-RS version 2.1. We decided to spin off the MVC work into a separate JSR, now called MVC 1.0. It is likely that MVC 1.0 will define integration points with JAX-RS, but it will be up to the MVC EG group to define those. In addition, MVC 1.0 may support other types of controllers.
