Release 11 of Vibur DBCP brought many new features and performance enhancements, some of which are:
* Added logTakenConnectionsOnTimeout configuration option - allows in case of Connections exhaustion the application
to log all currently taken Connections with optionally including the full stacktrace for each taken Connection.
* Added invocationHook configuration option - a programming hook that allows the application to intercept all method
calls on all proxied JDBC interfaces.
