ExtensionAddHandler rollback handling passes the extension resource to ExtensionRegistry.remove when the API wants the root resource. This results in this failure:

Also, ExtensionResource should not return null from getChildren. Fixing that would eliminate the NPE but the rollback handling wouldn't work properly with the wrong object being passed in.
