[wildfly-dev] EE Features in WildFly Core

[Brian Stansberry]

I think for now, 1 - Do Nothing because the provisioning stuff is soon
enough going to allow something like 3. How?

A package related to elytron will have an optional dependency on a package
related to jaspic. Since it's optional it won't be included in a default
provisioned server.

A jaspic "feature" (part of the elytron configuration) will have a hard
dependency on that jaspic package. So if the provisioning spec includes
that feature, the package will be included in the install.

Something in full could possibly also have a hard dependency on jaspic.
(Maybe not I don't know the EE details.) If so having that thing present
would also ensure the jaspic package is included.

The semi-edge case is the user provisions something with no hard dep on the
jaspic package, and then wants to come along with the CLI/HAL and configure
jaspic. Won't work. The management handlers should deal with that with some
nice error message.

Another variant is the jaspic package is an optional dep but is included by
default, avoiding the semi-edge case. So the dist is bigger than needed,
but the provisioning tool makes it easier to exclude it than it is now,
since the provisioning file can declare that the jaspic package isn't
wanted via a simple exclude element.

Bottom line is I think the provisioning tooling is going to ease the pain
of slimming enough that jumping through hoops to make our feature packs
smaller becomes less necessary.
