--- Comment #2 from Jonathan Leech <jonat...@gmail.com> --- The DataSource or the ConnectionPool should also own the Driver instance, rather than the PooledConnection object. That a new instance of the Driver is instantiated via reflection for every Connection the pool creates is benign in most cases and catastrophic in others (e.g. Apache Phoenix will create a set of zookeeper connections for each instance of PhoenixDriver, which blows up spectacularly). Standard JDBC has the DriverManager create the single instance of the driver. Tomcat-dbcp seems to get it mostly right, although I think Java's DriverManager may create an instance of the Driver, and each pool may create a redundant one. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
