(was: @ewencp, thank you for your help.
I've started this task and all in all my conclusion is that we should delay this until the release of slf4j 1.8 (alpha2 is already out), as there are some log4j features that are being used but not part of slf4j, such as the LogManager in Log4jController or the Fatal log level.
It is a bit hard to work around these effectively and without breaking behaviour. Best I know is we could use error level instead of fatal for the time being or we could separate off Log4jController into its own module and try to load it in runtime if log4j is being used to get rid of the hard log4j dependency, but these are quite hacky and I'm not sure if it's worth the effort now as we have a workaround for the original issue. Please let me know what you think.)
