I took a look at the Category source, and it would appear ObjectRenderer is
called there (and not by the appenders) to create the LoggingEvent:
protected
void forcedLog(String fqn, Priority priority, Object message, Throwable t)
{
String s;
if(message instanceof String) {
s = (String) message;
} else {
s = myContext.rendererMap.findAndRender(message);
}
callAppenders(new LoggingEvent(fqn, this, priority, s, t));
}
So, unless the appearance here is very misleading, ObjectRenderer is just a
log4j alternative to toString(), presumably so that the latter is preserved
for other use by the application.
Thanks,
