The Apache Commons Pool team is pleased to announce the release of Apache
Commons Pool 2.8.1.
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 maintenance release (Java 8).
