java.lang.Object | +--java.rmi.server.ObjID
An ObjID is used to identify remote objects uniquely
in a VM over time. Each identifier contains an object number and an
address space identifier that is unique with respect to a specific host.
An object identifier is assigned to a remote object when it is exported.
If the property java.rmi.server.randomIDs is true, then the
object number component (64 bits) of an ObjID created with the
no argument constructor will contain a cryptographically strong random
number.
