             Summary: Create a service to install a dynamic 'wildflyee.api' module
                 Key: WFCORE-4621
                 URL: https://issues.jboss.org/browse/WFCORE-4621
             Project: WildFly Core
          Issue Type: Enhancement
          Components: Server
            Reporter: Brian Stansberry
            Assignee: Jeff Mesnil


Follow up on WFCORE-4612 by removing the list of detailed optional dependencies added there and instead have a service that installs a dynamic 'wildflyee.api' module that optional depends on all those. Then ExternalModuleDependencySpecService would add a dependency on that 'wildflyee.api' module.

Then the next step is the javaee.api module in full WildFly would become an alias to wildflyee.api.

The benefit to this is the content set for this 'ee.api' convenience module 

a) gets set in one place (vs the two places that WFCORE-4612 introduces)
b) is defined in core, which makes some sense as core utilizes the module for the ExternalModuleDependencySpecService use case.
c) External uses of 'javaee.api' can benefit from the WFCORE-4612 improvement; i.e. if they have slimmed the server such that some APIs are not present, javaee.api can still be used. They just can't be using any APIs that they slimmed away. 

A downside is maintaining an 'ee.api' modules is not a great fit for core.

The reason to use a dynamic module is a static module would be visible to Galleon, and with the standard passive+[1] provisioning scheme we use that would lead to Galleon provisioning the packages for all the EE APIs, regardless of whether the server config required them.

This is somewhat me brainstorming, so needs harder thought.
