This is valid in Java 5 and above. For example:

public static class Test {
public void test() {
Logger logger = new Logger() {
public void warn(Enum<?> message) {
// No-op, this is a mock

};
logger.warn(LogMessages.WRONG_PASSWORD);

Thank you. I now see how enums could be used but still don't see the advantage
of using them.
Just to be clear, given that there is a large existing user base for slf4j, we
can't modify the org.slf4j.Logger interface, except perhaps its javadoc. So any
extension of Logger needs to wrap/decorate org.slf4j.Logger. See for example,
XLogger [1] and XLoggerFactory [2] in the slfj-ext module.
