{@link KeyedObjectPool} implementations may choose to store at mostone instance per key value, or may choose to maintain a pool of instances for each key (essentially creating a {@link java.util.Map Map} of{@link ObjectPool pools}).

See {@link BaseKeyedObjectPool} for a simple base implementation.
