Tomcat doesn't call contextDestroyed() on JBoss shutdown

Hi,
For some reason when I shut JBoss down (either ^C or
shutdown script) Tomcat doesn't get a chance to call
contextDestroyed on my application. I have tried Tomcat
(standalone) 4.1.24 and 5.x and it works fine.

contextInitialised is called on startup, but contextDestroyed
remains uncalled.
