Concurrency

I have a 'Profile' (implementing MessageListener) that can be used
in multiple 'Session's. Since there is a thread per 'Session', I'm
assuming same 'Profile' object will be used by multiple session
threads. So the responsibility of thread-safety falls on profile
author. Right?

Is there a way to have a separate instance of profile per
session/thread. If not, could somebody educate me on it's pros/cons?

Thanks,
Harsh
