----------------------------------------
Summary: Incorrect resource passed into ExtensionRegistry.remove by
ExtensionAddHandler rollback handling
Key: WFCORE-4140
URL: https://issues.jboss.org/browse/WFCORE-4140
Project: WildFly Core
Issue Type: Bug
Components: Management
Reporter: Brian Stansberry
Assignee: Brian Stansberry
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.
