Activation setup problem

[tom phan]

Hi all,
I am currently trying to use the RMI activation libraries, and I started with the tutorial at
http://java.sun.com/j2se/1.3/docs/guide/rmi/activation/activation.1.html
The problem is, that I'd like to include this setup in a bigger program, and this implies not calling the System.exit(0) at the end of it. In that case, the program doesn't exit because threads are creating during the RMI server registration, and are still running (sample follows).

My question is: Is there a way to make the setup program exit without using System.exit()?
I checked other tutorials, and they all end up with that call.
Thank you for any suggestion.
