Note that "session" should be an implicit variable in every page,
already set to the user's session. You should not have to call
request.getSession in your page at all.

Usually this kind of thing happens because you have stored a reference
to a HttpServletRequest or HttpSession object somewhere you should not
have.

Can you:

a. Try to reproduce this issue with current Tomcat 7.0.47

b. Create a minimal, simple test WAR that demonstrates your problem
and post it somewhere

This is very unlikely to be a bug in Tomcat, but more likely a bug in
your own code.
