periodic (60 sec) problem from Vysper bosh servlet embedded in Tomcat 7.0.23

Tomcat Community,

I'm not sure if this should be posted here or on the Mina/Vysper list, but since the problem seems to be around Jetty Servlet3 continuation functionality within the context of Tomcat, I thought I'd post here first.

PROBLEM
We're using vysper in an embedded mode and have modified the BoshServlet to work in the context of our web application.  The Vysper bosh servlet seems to make use of Jetty servlet3 continuation, and we're getting the following stack trace every 60 seconds.  60 seconds seems to be the default bosh session timeout when there is no activity:

I'm not sure what's going on with the low-level servlet3 continuation stuff, but if anyone has any suggestions/recommendations, I'd greatly appreciate it.

Thanks,
Bob

Are you expecting the timeout to fire at this point, for those requests?

The request seems to think it is in the "DISPATCHING" state - is this
perhaps a long running stream of events?

I would also investigate whether that library supports a particular
version of Tomcat.
