             Summary: Update Capability ServiceTarget/Builder to use the new Service API.
                 Key: WFCORE-3982
                 URL: https://issues.jboss.org/browse/WFCORE-3982
             Project: WildFly Core
          Issue Type: Bug
          Components: Management
    Affects Versions: 6.0.0.Alpha4
            Reporter: Jeff Mesnil
            Assignee: Jeff Mesnil


Capabilities provided by service are installed with org.jboss.as.controller.CapabilityServiceTarget#addCapability that uses the deprecated org.jboss.msc.service.Service API.

It is not possible to provide a capability provided by the new org.jboss.msc.Service API.

In particular, there is a chicken and egg issue between org.jboss.as.controller.CapabilityServiceTarget#addCapability that needs an instance of the service(and returns a CapabilityServiceBuilder) and org.jboss.msc.service.ServiceBuilder#provides that creates a Consumer instance to pass to the service instance before this one is set with org.jboss.msc.service.ServiceBuilder#setInstance.

new workflow should be:

{code}
CapabilityServiceBuilder serviceBuilder = context.getCapabilityServiceTarget().addCapability(CAP_NAME);
Consumer<MyValue> consumer = serviceBuilder.provides(CAP_NAME);

Service myService = new MyService(consumer);

serviceBuilder.setInstance(myService)
     .install();
{code}
