> When UIViewRoot caching is enabled, the cached UIViewRoots can consume considerable memory across all of the users. The proposal is to extend the allowed values of the Servlet Initialization parameter:
> <param-name>org.apache.myfaces.trinidad.CACHE_VIEW_ROOT</param-name>
> to support, in addition to the current "true", and "false" values, the values of:
> "strong" UIViewRoot caching is enabled and always uses strong references to the cached UIViewRoot
> "soft" UIViewRoot caching is enabled and always uses soft references to the cached UIViewRoot, allowing the cached UIViewRoots to be purged if under memory pressure
> <classname> The fully qualified classname of an implementation of org.apache.myfaces.trinidad.util.ref.PseudoReferenceFactory returning any desired PseudoReference implementation.
> In addition, the value of "true" now uses the value of a PseudoReferenceFactory implementation registered under the service name "org.apache.myfaces.trinidad.CACHE_VIEW_ROOT" if one is registered, otherwise, it uses a strong reference, to duplicate the current functionality
