Many (most) of us don't want to introduce JDK logging into our projects. We are very happy with logging to our framework of choice via slf4j. I believe you've said before that JDK logging can easily be redirected to slf4j (just like it is redirect jcl to slf4j). If that really is the case, then I think it would make sense to switch Mina to JDK logging, since everyone can then log from Mina to wherever they want, without any complexity within Mina, or external dependencies. However, I haven't seen any code anywhere to actually do this -- perhaps you'd like to reference something that does this, or explain to the list how this could be done, or code it yourself if its not currently available? That would go a long way to "convincing" frameworks to switch to a logging system that few people actually use. Keep in mind this "solution" should take into account esoteric classloader situations (such as within application servers or OSGi runtimes). If it can be done, I think it would actually be a very useful and widely used component -- I know there are some other libraries I use that use JDK logging that I would love to redirect to log4j so I can manage all my logging from one place.
