Many new features and improvements since version 1.2:
The detection and logging of slow SQL queries and slow DataSource.getConnection() calls is now accompanied by an option that can detect and log queries returning ResultSets with size above a certain limit.
Improvements in the queries validation timeouts control.
Various other logging improvements and standardizations, including logging of the concrete SQL query parameters, if the underlying SQL query execution has thrown an exception.
poolReducerClass is now configurable. This is the fully qualified pool reducer class name. This setting is useful for applications that need to provide their own custom monitoring of the number of currently allocated in the pool connections, including their own logic for reducing the number of currently unused connections.
