/**
* DelegatingPoolAdapter is an abstract implementation of GemFire's {@link Pool} interface and extension of
* {@link FactoryDefaultsPoolAdapter} that delegates operations to the provided {@link Pool} instance.
*
* However, this implementation guards against a potentially null {@link Pool} reference by returning
* default factory settings for the {@link Pool}'s configuration properties along with default behavior for operations
* when the {@link Pool} reference is null.
