I used to get that exception occasionally for reasons I never quite
understood. Probably different ways of the session ending, by logout or
timeout or server restart... Anyway, I ignored the exception, figuring that
if the invalidation was already done I didn't need to repeat it. I have
this utility method in my Engine:
public void endSession(IRequestCycle cycle)
{
try {
restart(cycle);
}
catch (Exception ex) {
// Ignore it if the session was already invalidated.
log.debug(ex.getMessage());
}
}
I've been running like that for months with no bad effects that I know of.
Hmmm... looking back through my logs, I see that I'm not getting the
exception any more. I must've cleaned up something else since then. Maybe
that will get you started anyway... you can see when the exception is
occurring.
I call that method from a simple form-listener method in my login/logout
component.
