      1. change deployment scanner interval to 10ms <deployment-scanner scan-interval="10" ...}
      2. define byteman rule which holds down an unbound of a datasource for a bit
        1. add to standalone.conf byteman to be loaded [2]
        2. script.btm rule will be kind of [1]
      3. deploy some simple app which uses ExampleDS datasource
      4. start server and stop server (CTRL+C)
      5. you should see the exception from deployment scanner

      It happens time to time that deployment scanner can throw and log error [1] when server is shutting down.
      It's in case of clean startup and clean shutdown when error messages should not be shown. I can hit it when unbounding a datasource takes a bit longer and scan of deployment scanner hits that time.
