I think you're confusing PermGen with the old (aka tenured) generation. Only instances of java.lang.Class go into PermGen (plus some internal JVM structures); nothing ever "jumps the fence" into PermGen. It's impossible to prevent at least some objects from eventually migrating to the OldGen, since anything that persists long enough will end up there after some number of minor GCs. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
