We should move away from Java Util Logging.
It is well known that
using it is not recommended for performance and also classloading nightware reasons (see http://articles.qos.ch/thinkAgain.html for details on the matter).
(THIS IS ACTUALLY WRONG!)
It touches us through PETALSESBCONT-323 too for the classloading problems.
Also it could simplify our homemade MDC code (the ExecutionContext that is in easycommons-thread).
We should evaluate what to use, but slf4j and logback have a very good reputation in the java community.
