Their should be a generic way to start/stop/deploy/etc. I haven't looked into JSR-77 yet, maybe that's the one. But I'd propose to standardize on the command line instead of the Java API, which is hugely cumbersome in a heterogenous environment the apps commonly live in.

This seems a mistake to me, it's much more powerful to define such a Java API (or a REST API). With a Java API, it's easy enough to write a quick java app that can be called by a script, or to wrap the Java API in a REST API, a SOAP API etc.

Personally, I would love to see Java EE define a Java API for this, and a REST API.

This seems to me to be an impl detail?

This does seem too much for EE 7 :-)
