libcommons-pool-java 1.3-1ubuntu1 (i386 binary) in ubuntu intrepid

 Pool provides an Object-pooling API, with three major aspects:
  1. A generic object pool interface that clients and implementors can use to
     provide easily interchangeable pooling implementations.
  2. A toolkit for creating modular object pools.
  3. Several general purpose pool implementations.
