Scott,
Even before we consider new specs, we need to start thinking about moving to the Jakarta equivalent of CDI, JAX-RS, JSON-B, and JSON-P. Some of these APIs are available in Maven using the Jakarta Group and Artifact IDs, but not all of them. Since these should be exactly the same as the Java EE 8 versions, the move should be painless. But, will this require an update to our platform version? That is, do we need MP 3.x branch for this type of update? Or, would an MP 2.x update be sufficient?
(Didn't mean to hijack your thread... This is something I've been thinking about and your post caused me to put it in writing. And, your subject line was generic enough...)
