As I said, my project only contains the one version of log4j. (Unless Tomcat is sneaking something in that I'm not seeing.) I'm not sure how whether or not the jars are exploded makes a difference with package accessibility? Maybe there's something weird going on with the ClassLoader and the LoggerContext?
