Changes between 1.2.8 and 1.2.9*) Added a fail-fast option for pool initialization. If enabled, aRuntimeException will be thrown if there are errors during poolinitialization.*) Made the registration of the HikariCP MBeans optional. They nowdefault to not being registered. Registering them causes a minorperformance hit due to additional pool data collection inHikariDataSource.getConnection().*) Added the SQLException message to the log entry when an exceptionoccurs during physical connection acquisition.*) Implemented an orderly shutdown of the pool via the shutdown() methodon HikariDataSource.*) Listened to "Adele - Live At The Royal Albert Hall" on endless loop.
