Is your webapp ?
Are you using Session Listeners ?

Jules, thanks for your help on this. We are not using a SessionListener and unless is a default we did not configure a distributable session either. The object we want to put in the session is a Hashtable.

Otherwise, please post the stacktrace
It seems the NPE comes from our object. The new Jetty version seems to call equals() on what it wants to put into the session and the NPE occurs in our equals() method.
