The Jakarta Commons team is pleased to announce the release of version 1.1
of the Jakarta Commons Pool component.

Commons-Pool provides a generic object pooling interface, a toolkit for
creating modular object pools, and several general purpose pool
More info:

There were a lot changes since the 1.0.1 release on 12 Aug 2002.
    * A lot of corner cases were fixed.
    * Performance improvement by optimizing pool synchronization, the
      critical code paths were optimized by reducing pool synchronization
      but we also added more synchronization where needed.
    * New minIdle feature: the minimum number of objects allowed in the
      pool before the evictor thread (if active) spawns new objects.
      (Note no objects are created when: numActive + numIdle >= maxActive)
    * New maxTotal feature: a cap on the total number of instances
      controlled by a pool. Only for GenericKeyedObjectPool where
      maxActive is a cap on the number of active instances from the pool
      (per key).
    * UML Class & sequence diagrams.
    * This release contains bug fixes to all known issues.
