batch mode: Impossible to re-login after an error in the cleanup procedure

I am using the RFA java API to connect in batch mode to the exchanges.
Sometimes I get an IllegalArgumentException when I try to call the cleanup, to close the batch procedure. Afterwards it is not anymore possible to login again and any subsequent connections returns the message:
RSSLLoginHandler.respondToNewLoginRequest() - original msg did not have REFRESH, not sending a response.
At this point I have to kill the client application in order to have a new session working from scratch

One only has to send a single LOGIN request per connection. The warning message is indicating that a re-issue it submitted when a matching response is expected first. RFA performs a LOGIN and DIRECTORY request for every connection configured independent of what the application executes. The design behind is RFA is that the application only need send a single LOGIN and the API will replay and hide duplicate responses from each underlying session.
Batch Close requests require a list of valid handles to operate upon:
List<Handle> item_handles = new ArrayList<Handle> (...);
omm_consumer.unregisterClient (item_handles, null);It is faster to simply close the LOGIN stream than close each individual request.
