Manik Surtani updated JBCACHE-1082:
-----------------------------------

    Fix Version/s: 2.1.0.GA
                       (was: 2.0.0.GA)
                       (was: 2.0.0.CR3)

> Many use cases just place a single object in a Node.  Rather than going through the memory and performance penalties of using Maps for a single entry, we should:
> 1)  Create a reference to 2 Objects for key and value, as well as a Map.
> 2)  Only initialise/construct the Map if Node.putAll() is called, or when Node.put() is called with a second key/value pair
> 3)  Otherwise just hold the key/value pair as direct object refs.
> Would affect UnversionedNode and WorkspaceNodeImpl.
