HttpSessionListener in Tomcat 4.1.27 (or HttpSessionListener in general)

[Lukas Bradley <lu...@somnia.com>]

All,

When I attempt to access the HttpSession object within the
sessionDestroyed(), I get the following error.

DEBUG [StandardManager[]] (SessionListener.java:40) - sessionDestroyed()
StandardManager[] Session event listener threw exception
java.lang.IllegalStateException: getAttribute: Session already invalidated

        at java.lang.Thread.run(Thread.java:536)

Why would the HttpSessionEvent *seem* like it should have access to the
session that has just been removed, yet not be able to access it?  Is this a
Tomcat problem, or does the Servlet 2.3 spec simply want you to know that
some random session was just invalidated, but you can't get any information
about it.

Any help appreciated.
