Correct. As you stated, the logback API sits on top of SLF4J. There are no plans to change that. > This is unfortunate for those who have been using JSE 5 for some time > now, and still have not been able to fully take advantage of its > features (especially when it comes to the work of tedious logging). You do realize that the SLF4J API already supports parameterized logging up to 2 parameters? With an SLF4J logger you can write: Logger logger = LoggerFactory.getLogger(Wombat.class); Integer t; Integer oldT; Integer expectedT; logger.debug("Some message."); logger.debug("Temperature set to {}", t); logger.debug("Temperature set to {}. Old temperature was {}.", t, oldT); However, SLF4J does not support 3 or more parameters. So, you could not write: logger.debug("new={}, old={}, expected={}", t, oldT, expectedT); You would have to write: logger.debug("new={}, old={}, expected={}", new Integer[] {t, oldT, expectedT}); I believe that compared to the slight inconvenience above, breaking compatibility is a more serious concern. > I was really excited about SLF4J/Logback when this project started, but > without these new features (which would simplify and reduce my coding > effort) it just doesn't seem worth it to convert to this logging > framework (even though I really appreciate the clean Logback > implementation).

You might also want to check out the slf4j-migrator [1] which may help with your migration efforts, when and if you decide to migrate to SLF4J.
