022/**
023 * A minimal subclass of the standard Apache Commons Logging's {@code LogFactory} class,
024 * overriding the abstract {@code getInstance} lookup methods. This is just applied in
025 * case of the standard {@code commons-logging} jar accidentally ending up on the classpath,
026 * with the standard {@code LogFactory} class performing its META-INF service discovery.
027 * This implementation simply delegates to Spring's common {@link Log} factory methods.
