A minimal subclass of the standard Apache Commons Logging's LogFactory class, overriding the abstract getInstance lookup methods. This is just applied in case of the standard commons-logging jar accidentally ending up on the classpath, with the standard LogFactory class performing its META-INF service discovery. This implementation simply delegates to Spring's common Log factory methods.
