- Borrow SLF4J API which is the best of the best - InternalLoggerFactory now automatically detects the logging framework using static class loading. It tries SLF4J, Log4J, and then falls back to java.util.logging. - Remove OsgiLogger because it is very likely that OSGi container already provides a bridge for existing logging frameworks - Remove JBossLogger because the latest JBossLogger implementation seems to implement SLF4J binding - Upgrade SLF4J to 1.7.2 - Remove tests for the untestable logging frameworks - Remove TestAny
