[logback-dev] [JIRA] Commented: (LBCLASSIC-172) Use WeakHashMap instead of Hashtable in LoggerContext

[Ralph Goers (JIRA)]

Ralph Goers commented on LBCLASSIC-172:
---------------------------------------

In "normal" usage releasing loggers is a bad idea. First, it will result in some performance impact to the application. Since Loggers are usually associated with classes - and are often declared static to boot, "forgetting" them would cause all kinds of bad behaviors when a reconfiguration is performed.
