          interface for a pool of object instances, and a handful of base
          classes that may be useful when creating pool implementations.
          The API supports pooling of unique objects which can be requested
          via a key as well as pools where all objects are equivalent.

          GenericObjectPool} has many configuration options and can support

          connection pool.

          SoftReferenceObjectPool} has no limit on the number of objects in the
          pool, but the garbage collector can remove idle objects from the pool
          as needed.  There are also keyed versions of the first two.
