| Apache Commons Pool 2.7.0 RELEASE NOTES |
| 23 July 2019 |
| |
| The Apache Commons Pool team is pleased to announce the release of Apache Commons Pool 2.7.0. |
| |
| 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 feature release (Java 8). |
| |
| Changes in version 2.7.0 include: |
| |
| New features: |
| o POOL-370: Add org.apache.commons.pool2.PooledObject#getBorrowedCount(). Thanks to Mark Thomas, Gary Gregory. |
| o POOL-371: Add org.apache.commons.pool2.PooledObject#setRequireFullStackTrace(boolean). Thanks to Matt Sicker, Gary Gregory. |
| |
| Fixed Bugs: |
| o POOL-361: Move validation for newly created objects into create(). Fixes #23. Thanks to Pablo, Phil Steitz, Bruno P. Kinoshita. |
| |
| Changes: |
| o POOL-364: Update from Java 7 to Java 8. Thanks to Gary Gregory. |
| o POOL-365: Update ASM from 7.0 to 7.1 Thanks to Gary Gregory. |
| o POOL-366: Update optional library cglib from 3.2.10 to 3.2.12. Thanks to Gary Gregory. |
| o POOL-367: Fix typo in package private method name stopEvitor() -> stopEvictor() #22. Thanks to Per Lundberg. |

| create any objects. |

| maxTotal threads try to borrow objects with different keys at the same |
| time and the factory destroys objects on return. Thanks to Ivan Iliev. |

| 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. |
