             Summary: read-resource(include-aliases=true) handler always returns aliased children, even if no resource exists at the target address
                 Key: WFCORE-692
                 URL: https://issues.jboss.org/browse/WFCORE-692
             Project: WildFly Core
          Issue Type: Bug
          Components: Domain Management
    Affects Versions: 1.0.0.CR3
            Reporter: Paul Ferraro
            Assignee: Brian Stansberry


Just because an alias is registered doesn't mean a child resource necessarily exists at the target address.  The handler needs to validate that a resource actually exists at the target address rather than assuming it does.  This causes read-resource(recursive=true, include-aliases=true) to fail.

Here's an example:
I have a alias registered that translates:
/subsystem=infinispan/cache-container=*/local-cache=*/file-store=FILE_STORE
to:
/subsystem=infinispan/cache-container=*/local-cache=*/store=file

If I create a cache without a file cache store (which is perfectly valid), the corresponding read-resource operation returns a child for file-store=FILE_STORE, even though it returns no child for file=store (the target address), since no such child resource exists.

This is very problematic, since it makes aliases unusable if the target child resource is not always present.
