Nick Belaevski commented on RF-8203:
------------------------------------

Cause of the issue: JSF 2.0 always uses serailization for value expressions, while 1.2 tested them for implementation of StateHolder interface also.

> Extensive memory usage is reproducible for RF 3.3.x running under JSF 2.0 when a4j:support is used. 
> Heap analysis shows that org.ajax4jsf.component.EventValueExpression is stored in session (as part of component tree state) holding active references to view components, thus not allowing component tree to be reclaimed by GC.
