The Apache Commons Pool team is pleased to announce the release of Apache Commons Pool 2.9.0.
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 2.9.x requires Java 8 or above. Version 2.8.x requires Java 8 or above. Version 2.7.x requires Java 8 or above. Version 2.6.x requires Java 7 or above. Version 2.5.x requires Java 7 or above. Version 2.0 requires 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 minor release (Java 8). Changes in version 2.9.0 include: Changes: o POOL-387: Object factory destroy method should carry information on activation context. Thanks to Phil Steitz. o Update spotbugs from 4.0.6 to 4.1.3, #37, #41, #46. Thanks to Dependabot. o Update actions/checkout from v2.3.1 to v2.3.3 #56, #45. Thanks to Dependabot. o Update actions/setup-java from v1.4.0 to v1.4.2 #42. Thanks to Dependabot. o Update optional asm-util from 8.0.1 to 9.0 #44. Thanks to Dependabot.
