Repeated Calls of NearCache.getAll() Returns Different Copies of a Cached Object When the Cache is Configured with an Invalidation Strategy of "none"

Symptoms
When you call getAll() repeatedly on a near cache and the underlying cache objects have not changed, the same Java objects should be returned.
Consider an example where there is a single object in the cache. In the case where invalidation strategy is none, the first getAll() call returns a different object from all of the subsequent getAll() calls, which is incorrect behaviour. For all other invalidation strategies, the same object is always returned, which is the correct behaviour.
When comparing Java objects, note that "==" compares references and not values, and the equals() method compares the internal values.
