[jira] [Created] (MYFACES-3936) Flash object requires cleanup strategy when client window feature is used

Leonardo Uribe created MYFACES-3936:
---------------------------------------

             Summary: Flash object requires cleanup strategy when client window feature is used
                 Key: MYFACES-3936
                 URL: https://issues.apache.org/jira/browse/MYFACES-3936
             Project: MyFaces Core
          Issue Type: Bug
          Components: JSR-344
    Affects Versions: 2.2.5
            Reporter: Leonardo Uribe
            Assignee: Leonardo Uribe


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.
