Performance issue - LRUMap() in AjaxStateHolder in JSF?

Question

I am using SUN JSF1.2 and Richfaces 3.3.1 in our application. As apart of performance tuning added the below parameters in the web.xml

<context-param>
   <param-name>com.sun.faces.numberOfViewsInSession</param-name>
   <param-value>2</param-value>
</context-param>
<context-param>
   <param-name>com.sun.faces.numberOfLogicalViews</param-name>
   <param-value>2</param-value>
</context-param>

Still when i inspected the session object i saw that org.ajax4jsf.application.AjaxStateHolder was consuming almost 85%( Almost 10 MB) of the session memory. Even i tried to get the AjaxStateHolder object from session but not able to delete all the cached session.

I have searched the web, it was mentioned that is a problem exist in Richfaces.

Is there anyway to clear all those cached views from the LRMap.

I had a problem similar to what's stated here:

I needed to make some custom modifications for IE9 and adding tooltips to the calendar component, so I grabbed the source and modified protected static final int DEFAULT_NUMBER_OF_VIEWS = 16; to equal a value of 1.

I built the project using Maven 2. Maven 3 will not work.

Changing all the places where that constant is declared fixed the problem for me.
