22 October 2003 - Commons Pool 1.1 Released

ANNOUNCEMENT:

The Jakarta Commons Team is proud 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 implementations.

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.
