HashTable

[ted@xxxxxxxxxx (Ted Neward)]

So long as the stub on the client remains "alive" (that is, able to
communicate back to the server and renew its Lease), the object on the
server will also remain alive, guaranteed--the DGC portion of the RMI Specs
guarantee that. I can't see any reason why holding a Remote reference in a
HashTable would be a problem, except for the usual "what if the server
crashes" issue, and that's an issue regardless of whether the reference is
held in a HashTable or as a regular reference.
