Hi Les,

Thanks for getting back to me.  Your reply prompted me to dink around with
this a bit more.  I just created a stub ServletContextListener to see
whether jetty calls "contextInitialized" again after it recreates the
WebEnvironment during a reload and it appears that the
ServletContextListener.contextDestroyed(ServletContextEvent) gets called,
but that ServletContextListener.contextInitialized(ServletContextEvent) is
not called again.

That being the case, I think it's safe to assume, for now, that this is a
jetty issue and not a Shiro issue.  I'll be sure to post any work around I
find here in case someone else comes across this problem in the future.
