System.gc()

[Sai Prasad]

I set the reference to remote impl object at the client to null and called System.gc(). Immediately, Unreferenced() is invoked on the server side. I plan to implement this while user exits the system gracefully. I like to know what you feel about it. Thanks.

Seems like a good solution;
I would go for it than "LeaseValue"

It is unnecessary but harmless. If the client exits gracefully, it should call db.close() anyway and it is immaterial when Unreferenced is called (as you have already been able to do your cleanup). If the client does not exit gracefully, well, you will only find out when the lease expires anyway.
