/** If a JMS provider detects a serious problem with a <CODE>Connection</CODE>
  * object, it informs the <CODE>Connection</CODE> object's 
  * <CODE>ExceptionListener</CODE>, if one has been registered. 
  * It does this by calling the listener's <CODE>onException</CODE> method,

  * <P>An exception listener allows a client to be notified of a problem

  * <P>A JMS provider should attempt to resolve connection problems 
  * itself before it notifies the client of them.
