Method from java.io.ObjectStreamClass$WeakClassKey Detail:
public boolean equals(Object obj) { if (obj == this) { return true; } if (obj instanceof WeakClassKey) { Object referent = get(); return (referent != null) && (referent == ((WeakClassKey) obj).get()); } else { return false; } } Returns true if the given object is this identical WeakClassKey instance, or, if this object's referent has not been cleared, if the given object is another WeakClassKey instance with the identical non-null referent as this one.
public int hashCode() { return hash; } Returns the identity hash code of the original referent.

Method from java.io.ObjectStreamClass$WeakClassKey Detail:

 public boolean equals(Object obj) {
            if (obj == this) {
                return true;
            }
            if (obj instanceof WeakClassKey) {
                Object referent = get();
                return (referent != null) &&
                       (referent == ((WeakClassKey) obj).get());
            } else {
                return false;
            }
}

Returns true if the given object is this identical WeakClassKey instance, or, if this object's referent has not been cleared, if the given object is another WeakClassKey instance with the identical non-null referent as this one.

 public int hashCode() {
            return hash;
}

Returns the identity hash code of the original referent.
