Hi Mike,
Here is a problem I have been interested but haven't had the time to
investigate it fully. You might want to check it out.
Log4j uses a class called LoggingEvent to encapsulate the information sent
to appenders from categories. For cases of remote logging, the event is
serialized and sent across the network to a waiting server which
deserializes it and processes it.
If one is using log4j in a distributed environment, the client and the
server have to be in synch as to the serialization version of the event.
If a log4j upgrade involves changes to the event class, then all clients
and servers must be upgraded at the same time. Otherwise object
serialization errors occur. This can make log4j upgrades prohibitive in
such an environment.
It may be possible to make LoggingEvent serialization immuned to such
changes. It would require some investigation, probably starting with a
serialization document:
http://java.sun.com/j2se/1.3/docs/guide/serialization/index.html
Keep in mind that this is a JDK 1.3 doc. The solution should be compatible
with other JDKs as well. Basically the goal is to allow the server to
de-serialize an event even if the fields didn't match exactly. I'm not
sure how possible or practical it is, but it's what I'd be working on if I
wasn't still entrenched with the appserver package.

Ok, now that I have embarressed myself on the user list maybe I should
do something to change my ignorance of the codebase. I'm new to this
process, so bear with me if I ask ignorant questions.
I don't really have any features I'd like to add. But I want to help.
Maybe I can help fix a bug or two. Should I just grab one, or should
someone assign me one that'll help me get my feet wet.
Thanks,
/mike
