there are at least 2 different views what does it mean to "integrate JCache
with Java EE":

1. Expose JCache concepts in a managed way - basically what Payara (and I
think TomEE?) has done. From the surface this looks like a relatively low
effort. (but it could still creep out - e.g. what about different scopes?
Request-specific caches, various defaults, etc.)

2. Integrate JCache with other concepts from Java EE: 2nd level JPA cache
is a nice example. I am sure there are more. One would have to go through
all Java EE specs and think where an integration could make sense. This
could be a massive effort with overlaps to different areas of Java EE.
