I wasn't aware that Loggers can be configured outside of LoggerContext. I've never done something like this. This makes the whole issue a lot more complex than I thought. It's solvable but rather complex - the state of a logger would need to be handled detached from the Logger itself. Urgs. I agree that this isn't simply an issue of WeakHashMap vs Hashtable. Solving this issue at *some* time should be kept in mind, though. Just for the sake of completeness: is there any other state beside level and appenders? And yes, Holger is right about SoftReferences. was (Author: jhuxhorn): Oh dear, now I understand the problem. I wasn't aware that Loggers can be configured outside of LoggerContext.

Use WeakHashMap instead of Hashtable in LoggerContext -----------------------------------------------------
Key: LBCLASSIC-172 URL: http://jira.qos.ch/browse/LBCLASSIC-172 Project: logback-classic Issue Type: Bug Components: Other Affects Versions: 0.9.18 Reporter: Joern Huxhorn Assignee: Logback dev list Fix For: unspecified
Preventing garbage-collection of unused Loggers is a bad idea. The following code should not fail: for(int i=0;i<10000000;i++) { LoggerFactory.getLogger("Foo."+i).debug("Foo!"); }
