Information in this document applies to any platform.
In Oracle JDBC Driver 188.8.131.52 or later, connectionClosed / connectionErrorOccurred events are not raised when a logical connection is closed.
This results in possible connection leak in some connection pool managers which are used in connection events implemented by javax.sql.ConnectionEventListener.
If using Universal Connection Pool (UCP), connection leak does not occur since UCP does not use these connection events for managing connections.
