com.sun.jini.jeri.internal.runtime.WeakKey
WeakKey objects are used by the object table to hold weak references to DGC-enabled remote objects in the exported object table, so that such a remote object with no known client references may be (locally) garbage collected. In order for WeakKey objects to be used as keys in the object table, this class extends java.lang.ref.WeakReference to override the hashCode and equals methods such that WeakKey objects hash and compare to each other according to the identity of their referents. The identity-based comparison is necessary to insulate the runtime from arbitrary remote implementation classes' notions of object equality. @author Sun Microsystems, Inc.
