Webconsole branding does not work

I've followed the documentation in the website to brand my webconsole however it does not work. I've verified that my fragment bundle attaches to the karaf webconsole bundle and provided all the files needed. It simply does not work. I've done this for plain felix webconsole and it works fine. It must be related with the karaf repackaging of webconsole.

I've checked online and found the http://karaf.922171.n3.nabble.com/Can-t-brand-the-webconsole-td4038868.html. The problem is the same actually. I've also found this example at https://github.com/liveSense/org.liveSense.karaf/tree/master/webconsole-branding which seems for a previous version. The only difference here is that JaasSecurityProvider.java is provided also and I'm not doing this (this file in the new version is not in the same place anyway...)
