jdk.rmi.activation.ActivationMonitor
An ActivationMonitor is specific to an ActivationGroup and is obtained when a group is reported active via a call to ActivationSystem.activeGroup (this is done internally). An activation group is responsible for informing its ActivationMonitor when either: its objects become active or inactive, or the group as a whole becomes inactive.

active-objectclj
(active-object this id obj)Informs that an object is now active. An ActivationGroup informs its monitor if an object in its group becomes active by other means than being activated directly (i.e., the object is registered and "activated" itself).
id - the active object's id - java.rmi.activation.ActivationID
obj - the marshalled form of the object's stub - java.rmi.MarshalledObject
throws: java.rmi.activation.UnknownObjectException - if object is unknown
Informs that an object is now active. An ActivationGroup informs its monitor if an object in its group becomes active by other means than being activated directly (i.e., the object is registered and "activated" itself). id - the active object's id - `java.rmi.activation.ActivationID` obj - the marshalled form of the object's stub - `java.rmi.MarshalledObject` throws: java.rmi.activation.UnknownObjectException - if object is unknown
inactive-groupclj
(inactive-group this id incarnation)Informs that the group is now inactive. The group will be recreated upon a subsequent request to activate an object within the group. A group becomes inactive when all objects in the group report that they are inactive.
id - the group's id - java.rmi.activation.ActivationGroupID
incarnation - the group's incarnation number - long
throws: java.rmi.activation.UnknownGroupException - if group is unknown
Informs that the group is now inactive. The group will be recreated upon a subsequent request to activate an object within the group. A group becomes inactive when all objects in the group report that they are inactive. id - the group's id - `java.rmi.activation.ActivationGroupID` incarnation - the group's incarnation number - `long` throws: java.rmi.activation.UnknownGroupException - if group is unknown
inactive-objectclj
(inactive-object this id)An activation group calls its monitor's inactiveObject method when an object in its group becomes inactive (deactivates). An activation group discovers that an object (that it participated in activating) in its VM is no longer active, via calls to the activation group's inactiveObject method.
The inactiveObject call informs the ActivationMonitor that the remote object reference it holds for the object with the activation identifier, id, is no longer valid. The monitor considers the reference associated with id as a stale reference. Since the reference is considered stale, a subsequent activate call for the same activation identifier results in re-activating the remote object.
id - the object's activation identifier - java.rmi.activation.ActivationID
