> As per summary above. If you have a browser open to the web console, and create a queue it works OK. However, if you then restart the broker adn then try and perform an action like deleting the queue (from the web console) then you'll see the NPE in the broker's log.

> I think this has something to do with stale session secrets, and is a consequence of support that was put in to protect ActiveMQ against CSRF (cross-site request forgery) attacks. The original CSRF error was alarming; this error, however, is a plain old NPE and we should fix it.
