> Under JDK / JRE 9 (tested with ea+149), it is impossibile to register the servlet via http-whiteboard.
> Steps to reproduce the problem:
> 1. Delete the folder data
> 2. Start karaf {code}bin/karaf{code}
> 3. Install feature http-whiteboard {code}feature:install http-whiteboard{code}
> 3. Copy the attached ServletTest.jar to $KARAF_HOME/deploy. The blueprint configuration tells karaf to register a servlet under the alias "/hw".
> 4. Open the browser and go to http://localhost:8181/hw, you will get an error.
> And ERROR message as follows will be logged in the data/log/karaf.log.
