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
