Not sure I'm worried about it atm, but this might be a good place for custom log extensions, so we could specific
a more detailed logging format that would include all this. So we could config something like:


log4j.appender.AuditAppender.conversionPattern=%{entityTimestamp} principalType=%{principalType} principal=%{principal} ..."

Not entirely sure what all log4j setup it would need to that. Maybe just a custon http://logging.apache.org/log4j/2.x/manual/extending.html#Lookups ?
