Description

In 2.2.x a change was done to Flash object, so now it uses the client window id and store the token into session instead use a cookie like it was done in 2.1.x/2.0.x

The problem is there is no cleanup strategy in place. So if you create n client window ids, there are n tokens in session and the session will only be cleaned up when the session is invalidated.

The solution is use a LRU map to hold the tokens, so when a client window / token is discarded, the objects stored in Flash scope associated to that couple could be removed.
