Unfortunately, the entire premise of that blog is flawed. The statement: "Objects in the permanent generation are never garbage collected; that is, under normal circumstances when the jvm is started with normal command line parameters." is just blatantly false. Why the author believes so is never made clear, but it is clear from his later blog that his supposed "solution" has nothing to do with his problem. If you want evidence that the PermGen actually is collected, start Tomcat with a large heap and JMX enabled, run some requests through a reasonably complex app such as Lambda Probe, and look at the PermGen with JConsole. Undeploy the add and force some GCs - more than one may be necessary - and the PermGen size will decrease (but probably not by much). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
