Description

The current DBCP component that ships with ActiveMQ is version 1.4. It dates from Feb 2010.

After fours years of inactivity a number of releases were made in the last twelve months to the DBCP component. The most recent version, 2.1, was released on Feb 23rd 2015.

Personally, I am seeing weird behavior with the DBCP 1.4 component when using it as a lease locker with KahaDB. When a connection is dropped the DBCP component doesn't always handle it correctly which manifests itself as a lease lock failure from the broker's standpoint.
