             Summary: Deprecate OperationContext.getRootResource(); provide variant to get a read only view of an addressed branch of the Resource tree
                 Key: AS7-3590
                 URL: https://issues.jboss.org/browse/AS7-3590
             Project: Application Server 7
          Issue Type: Task
          Components: Domain Management
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
            Priority: Critical
             Fix For: 7.1.1.Final


OperationContext.getRootResource() is very expensive as it clones the entire model in order to provide a defensive copy that callers can't use to mutate parent resources.

In almost all cases the caller then navigates to a lower level of the tree to read. The OperationContext should provide a method to do this for them, restricting the cost of defending against writes to the portion of the tree the caller actually cares about.
