David Lloyd commented on JBLOGGING-118:
---------------------------------------

If you don't want this effect to happen, then you should either (a) install jboss-logging server-wide, or (b) don't use the JUL backend; instead use log4j or logback or something.

> Subclass of java.util.logging.Level creates PermGen memory leak if webapp provides jboss-logging.jar inside a webapp. This happen most likely in Tomcat and hot-redeployment stops working after few times out of PermGen memory.
> It's a commonly known side effect of JDK logging library, projects should not inherit Level class. 
> See this discussion and github pull request where I have fixed this problem.
