Sure; I'm starting on it now. However, Jean-Francois found a HttpSession javadoc that
specifies throwing an IllegalStateException in getLastAccessedTime(). If that is in
the final spec, the 9077 patch algorithm will not work. I'll work on it anyway in
case the exception's not in the final spec.
As a backup, I've attached a patch that restores your earlier removal of the logout
code.
