      protected void callConnectionEventListeners​(int eventType, java.sql.SQLException sqlException)
      Notifies all registered ConnectionEventListeners of ConnectionEvents. Instantiates a new ConnectionEvent which wraps sqlException and invokes either connectionClose or connectionErrorOccurred on listener as appropriate.
      Parameters:
      eventType - value indicating whether connectionClosed or connectionErrorOccurred called
      sqlException - the exception being thrown
