Thank you vickyk!

When I invoke this function in ManagedConnection:

void connectionClosedEvent() 
  |    {
  | 		  Iterator it = connectionListeners.iterator();
  | 		  while (it.hasNext())
  | 		    {
  | 		    ConnectionEventListener listener = 
  | 		      (ConnectionEventListener) it.next();
  | 		    ConnectionEvent temp = new ConnectionEvent(this, ConnectionEvent.CONNECTION_CLOSED);
  | 		    listener.connectionClosed(temp);		      
  | 		    }
  | 	 }
when it arrives at lstener.connectionClosed(temp), the following error appears:
20:11:48,484 INFO  [NoTxConnectionManager] Throwable from unregisterConnection
  | java.lang.IllegalStateException: Trying to return an unknown connection2! null
  | 	at org.jboss.resource.connectionmanager.CachedConnectionManager.unregisterConnection(CachedConnectionManager.java:342)
  | 	at org.jboss.resource.connectionmanager.NoTxConnectionManager$NoTxConnectionEventListener.connectionClosed(NoTxConnectionManager.java:88)

  |     .................
  | 20:11:48,531 INFO  [NoTxConnectionManager] Unregistered handle that was not registered! null for managedConnection: com.jca.FileManagedConnection at 5f62a9

Then I go on it invoke connectionClosedEvent() again!! I really don't know why. This time the console prints the following Info:
