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.
