> 1) Add support for checking the Application Map, similar to the Session Map checking
in JIRA-1245 by adding "application" as one of the values allowed in the system property.

> The value can be retrieved programmatically by calling StateUtils:
>   public static boolean checkApplicationSerialization(ExternalContext extContext)
> 2) Increase the robustness of Serializability testing for Application and Session Maps
by not simply testing that the keys and values passed to the Maps implement Serializable,
but by actually attempting to Serialize the keys and values.  This catches cases where the
Object implements Serializable but itself contains unSerializable objects--for example a HashMap.
> This service is available through the CollectionUtils function:
>   public static <K,V> Map<K, V> getCheckedSerializationMap(Map<K, V>
> 3) Add a TransientHolder class for Objects that are required to be Serializable (for
example, they need to be added to the Session Map on a Servlet Engine configured for High
Availability), but, in fact, should not be Serialized.
> 4) Fix the ChangeManager intialization in the RequestContext to ensure that it is added
to the Application Map using a TransientHolder if the ChangeManager implementation is not
