Warning during replacement of deployment

Using Wildfly 10.1.0-Final on Solaris SPARC with Oracle JDK 1.8.0.

I redeploy my war file by removing the old one from the deployments folder and copying the new one there afterwards.

Now I noticed that there is a new Warning I've not seen before.What does this mean? Anything I can do to avoid this message?
