Hi,
Thanks for your reply.
Just wanted to confirm the following:

I suspect too. If I read the changelog for Tomcat 7.0.7 for Coyote I see that
this issue has been resolved there.
Maybe something similar is happening in Tomcat 6 also (I verified it for 6.0.29
and 6.0.33).

I built a new Tomcat 7.0.23 and now the second CometRead doesn't occur. Instead,
a CometEnd event is fired properly, so this seems to be fixed.
