Don’t know if this can help, but I was able to replicate the issue described in ticket 13971 by writing a simple UI with push enabled and transport = Transport.LONG_POLLING (see the attached Eclipse project).
After starting Tomcat 7:
- I open the UI in my web browser (Chrome, FWIW)
- I wait for the background thread to finish (3 sec.)
- I refresh the page
In this way I obtain the error sistematically. Switching transport to STREAMING seems to solve the problem (at least I was not able to reproduce it) but it creates other issues (on my webapp I switched to LONG_POLLING because with STREAMING I was experiencing a similar error when invalidating the http session, this is not shown in my project).
Thank you,
