I would try the following:
a) temp. disable any installed Virus engine or Firewall and test again
if that does not help
b) see this post in the related thread Fix for Jetty error when running on host with many cores - #13 by hakan
Then try again. Delete the content of OpenHab log.txt before restarting. In case of errors still happen re-upload Openhab log.txt with new entries.
The log files shows that the service was started on port 8080 but you are not able to connect ? Do you get a timeout or an error message ?
