Is there a way to clear logger entries from the Hierarchy class's internal Hashtable?
The issue I am trying to get around deals with the way in which I am creating loggers for my User object. The Logger is an instance variable and is created by: Logger.getLogger( "session." + user + "_" + session ). The combination username plus HTTP session id will be pretty unique. After looking through the code for LogManager, DefaultLoggerRepository, and Hierarchy I have seen no place where the loggers are ever cleaned up (once called they remain in the hierarchy's hashtable, thus preventing garbage collection). I am afraid these log4j loggers will in essence become a memory-leak, "clearable" only when the VM is shutdown. I understand that in the normal course/usage of log4j this is excatly what you probably want to happen. But in my scenario, it can potentially be pretty detrimental. Is there something I missed; someway to clear an individual entry from this hashtable? If not, looks like I'll have to subclass or edit Hierarchy to add a removeLogger method. What additional clean-up type methods should I call on the Logger in that case? Logger.removeAllAppenders()? Any others?
