| Apache Commons Pool 2.5.0 RELEASE NOTES |
| |
| The Apache Commons Pool team is pleased to announce the release of Apache Commons Pool 2.5.0. |
| |
| Apache Commons Pool provides an object-pooling API and a number of object pool implementations. |
| Version 2 contains a completely re-written pooling implementation compared to the 1.x series. |
| In addition to performance and scalability improvements, version 2 includes robust instance |
| tracking and pool monitoring. Version 2 requires JDK level 1.6 or above. |
| |
| No client code changes are required to migrate from versions 2.0-2.3 to version 2.4.3. |
| Users of version 1.x should consult the migration guide on the Commons Pool web site. |
| |
| NOTE: The MBean interfaces (DefaultPooledObjectInfoMBean, GenericKeyedObjectPoolMXBean |
| and GenericKeyedObjectPoolMXBean) exist only to define the attributes and methods |
| that will be made available via JMX. They must not be implemented by clients as |
| they are subject to change between major, minor and patch version releases of |
| Commons Pool. Clients that implement any of these interfaces may not, therefore, |
| be able to upgrade to a new minor or patch release without requiring code |
| changes. |
| |
| This is a patch release, including bug fixes only. |
| |
| Changes in version 2.5.0 include: |
| |
| New features: |
| o POOL-332: ObjectPool and KeyedObject pool should extend Closeable. |
| o POOL-335: Make abandoned logging stack trace requirements configurable. This also reverts |
| the default behavior introduced by POOL-320. |
| |
| |
| Changes: |
| o POOL-331: Update from Java 6 to 7. |
| o POOL-333: Update optional dependency asm-util from 5.2 to 6.0. |
| o POOL-334: org.apache.commons.pool2.impl.ThrowableCallStack.Snapshot is missing serialVersionUID. |
| |

| patches, or suggestions for improvement, see the Apache Apache Commons Pool website: |

| |
| Changes in version 2.4.3 include: |
| |
| New features: |
| o POOL-320: Use more efficient stack walking mechanisms for usage tracking when possible. |
| |
| Fixed Bugs: |
| o POOL-328: Documentation with repeated words (sources, tests, and examples). Thanks to Lorenzo Solano Martinez. |
| o POOL-317: Correction of default value of softMinEvictableIdleTimeMillis in BaseObjectPoolConfig. Thanks to KeiichiFujino. |
| o POOL-309: Fix misspellings from "destory" to "destroy". Thanks to jolestar, Roopam Patekar. |
| o POOL-306: Ensure BaseGenericObjectPool.IdentityWrapper#equals() follows the expected |
| contract for equals(). Thanks to Adrian Crum. |
| o POOL-303: Ensure that threads do not block indefinitely if more than maxTotal |
| threads try to borrow an object at the same time and the factory fails to |
| create any objects. |
| o POOL-310: Ensure that threads using GKOP do not block indefinitely if more than |
| maxTotal threads try to borrow objects with different keys at the same |
| time and the factory destroys objects on return. Thanks to Ivan Iliev. |
| o Ensure that any class name used for evictionPolicyClassName represents a |
| class that implements EvictionPolicy. |
| o POOL-315: Add a configurable delay (default 10 seconds) to wait when shutting down |
| an Evictor to allow the associated thread time to complete and current |
| evictions and to terminate. Thanks to KeiichiFujino. |
| o Ensure that a call to GKOP preparePool() takes account of other threads |
| that might create objects concurrently, particularly the Evictor. |
| |
| Changes: |
| o POOL-280: Small refactoring of borrowObject() to reduce code duplication. Thanks to Jacopo Cappellato. |
| o POOL-307: Replace inefficient use of keySet with entrySet in GKOP. Thanks to Anthony Whitford. |
| o POOL-322: Update optional cglib library from 3.1 to 3.2.5. |
| o POOL-323: Update optional OW2 ASM from 5.0.4 to 5.2. |
