I just notice this today, and see the same thing in promoted build 27.
If i deploy an app to a standalone instance that is not running, or a cluster that has non-running
instance, DFDeployment Status will return a WARNING status.
The Warning itself just says: "Application deployed with name i18n-simple".
But when i check server.log, there is no WARNING at all.
The only log from deploying the app is:
dID=112;_ThreadName=admin-thread-pool-4848(3);|i18n-simple was successfully deployed in
For undeploy, it again give WARNING status, but the statusString is empty.
This makes it very odd when seen in GUI.
If i deploy that to a running instance, it is fine.
