Ubuntu - ServiioConsole : Unsupported major.minor version 52.0

After reinstall to current Ubuntu release I started to have troubles with starting Serviio, throwing me following error message>

 Exception in thread "main" java.lang.UnsupportedClassVersionError: org/serviio/console/ServiioConsole : Unsupported major.minor version 52.0

Could not find the main class: org.serviio.console.ServiioConsole. Program will exit.

I got to the conclusion that there is a problem with java, therefore tried to update to most current version by adding java ppa to the repository, according to: http://www.webupd8.org/2014/03/how-to-install-oracle-java-8-in-debian.html


...and voilla, Serviio runs like a charm!
