@mustafa Below are the steps to override the default jetty favicon.

• From JETTY_HOME move into lib folder
• 'mkdir -p org/eclipse/jetty'
• Move the official Jans favicon into the folder created above(org/eclipse/jetty)
• Then run 'jar -uf jetty-server-VERSION.jar org/eclipse/jetty/favicon.ico' where VERSION is the current jetty version.
  eg. jar -uf jetty-server-11.0.15.jar org/eclipse/jetty/favicon.ico

I think we need this apply during the setup process.
