public final class ImmortalMemory

extends MemoryArea

ImmortalMemory is a memory resource that is shared among all threads. Objects allocated in the immortal memory live until the end of the application. Objects in immortal memory are never subject to garbage collection, although some GC algorithms may require a scan of the immortal memory. An immortal object may only contain reference to other immortal objects or to heap objects. Unlike standard Java heap objects, immortal objects continue to exist even after there are no other references to them.
