Does Tomcat reuse parameterMap?

[Nikita Tovstoles <ni...@eviltwinstudios.net>]

In Tomcat, do multiple HttpServletRequest objects share same 
parameterMap instance? If so, and access to that instance is not 
synchronized, doesn't that mean that one request can get another 
requests parameters?

It can be reused - but it is only used in by a single request at a time. A 
single request is bound to a thread. So it is thread safe.

Now if you have listeners that is assigning the value of the map or the 
servlet request to something else. And that something else lives longer than 
the life of a request - then bad things will probably happen.
