I do not know why you want to create a thread in your servlet. A servlet
container is a controlled runtime with the container managing
instantitiaion and threads for requests. Explicit threading may conflict
with the container.
I suggest that you've a relook at your design. Your design does not seem
to be sensitive to the specification.

You should use the <get/set>MaxInactiveInterval of HttpSession to let
the container invalidate the sessions for you.
Hopefully, by changing the design, you'll not have the above
requirement.
Cheers!
