jdk.rmi.activation.ActivationInstantiator
An ActivationInstantiator is responsible for creating
instances of activatable objects. A concrete subclass of
ActivationGroup implements the newInstance
method to handle creating objects within the group.
An ActivationInstantiator is responsible for creating instances of `activatable` objects. A concrete subclass of ActivationGroup implements the newInstance method to handle creating objects within the group.

(new-instance this id desc)The activator calls an instantiator's newInstance method in order to recreate in that group an object with the activation identifier, id, and descriptor, desc. The instantiator is responsible for:
determining the class for the object using the descriptor's getClassName method,
loading the class from the code location obtained from the descriptor (using the getLocation method),
creating an instance of the class by invoking the special
activation constructor of the object's class that takes two
arguments: the object's ActivationID, and the
MarshalledObject containing object specific
initialization data, and
returning a MarshalledObject containing the stub for the remote object it created
id - the object's activation identifier - java.rmi.activation.ActivationID
desc - the object's descriptor - java.rmi.activation.ActivationDesc
returns: a marshalled object containing the serialized
representation of remote object's stub - java.rmi.MarshalledObject<? extends java.rmi.Remote>
throws: java.rmi.activation.ActivationException - if object activation fails
