Hi, I'm wondering whether someone has had this problem before, because I couldn't find anything about it in the forums. From time to time in my logs I see this exception:

class is not serializable. Now I thought I would just replace the Log4J version that ships with JBoss 4.0.4 with a newer version (Log4J 1.2.13), but somehow the problem persists. What I replaced were the log4j.jar in server/all/lib, but not the log4j-boot.jar in the servers lib directory. I guess these are the classes that are still loaded first, and thus still causing the problem. But I am not sure on how to replace this log4j-boot.jar (if it's the source of the problem at all)? Could I just replace it with the normal log4j.jar?
