Not true - classes do get cleaned up, if there are no references to them. If you turn on enough GC tracing options, you can see this happening, especially with anonymous classes, which are created and destroyed with great frequency. The problem is retained references to either the associated classloader or instances of java.lang.Class; as long as these exist, the class objects won't go away. (The reports that JRockit doesn't run into the OOME is either a bug in JRockit - releasing classes while there are still references to them - or an aspect of JRockit not segregating java.lang.Class instances in a relatively small space separate from the rest of the heap.) - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
