BTW, I've started looking at both Ralph and Joern's proposals.
Thanks. The main difference is that the Message is assumed to reach the appender implementations unchanged, i.e. not transformed into a String. That way, appenders can implement special handling of certain known (to the appender) Message implementation. Only an appender like ConsoleAppender would actually use the formatted message. A specifically implemented DBAppender, for example, could store certain application-specific fields in special tables. Or, as in Ralphs case, if I remember correctly: take the structured data (a map) and store the various entries as required by the RFC. Cheers, Joern.
