jsecurity-user: is it possible to force a discard a "remember me" cookie?

[Brad Whitaker]

Is it possible to force JSecurity to "forget" a subject that has 
previously been remembered?

This is an issue for me only in "development" mode and shouldn't occur 
in a production environment. The problem is that I often start a 
development session with an empty user database but the browser comes to 
the site with a cookie. I end up getting a Principal that I don't know. 
I would like to discard the cookie at this point. Is this possible? Or 
is there a better way to deal with this issue (other than clearing the 
cache on the browser)?

Thanks,

Brad
