             Summary: ExtensionRemoveHandler logs client mistakes
                 Key: WFCORE-1042
                 URL: https://issues.jboss.org/browse/WFCORE-1042
             Project: WildFly Core
          Issue Type: Bug
          Components: Domain Management
    Affects Versions: 2.0.0.CR6
            Reporter: Brian Stansberry
            Priority: Minor


If a user tries to remove an extension when there are still subsystems present that come from that extension, a stack trace appears in the log:

{code}
01:02:23,542 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 2) WFLYCTL0013: Operation ("remove") failed - address: ([("extension" => "org.jboss.as.test.hc.extension")]): java.lang.IllegalStateException: WFLYCTL0219: An attempt was made to unregister extension org.jboss.as.test.hc.extension which still has subsystem HC registered

{code}

That's really just a client mistake and there's no reason to log it in the server. ExtensionRemoveHandler can catch the ISE thrown by ExtensionRegistry.removeExtension and convert it to an OperationFailedException.
