Lars this seems like a good development to me. I presume we will still be able to override with an external log4j config. Sometimes its more convenient to rotate by time (eg month) than by size.
I presume all the exception dumps (ie not "real" logs) are going to end up in catalina which is fine. We can work on catching them piece by piece.
