--------------------------------------------
Summary: "No future" warning in the log
Key: DIRAPI-388
URL: https://issues.apache.org/jira/browse/DIRAPI-388
Project: Directory Client API
Issue Type: Bug
Affects Versions: 2.1.2
Reporter: Alexander Prishchepov
We run queries that return single result.
Our code closes cursor after first Entry is retrieved.
We see a lot of "MSG_04165_NO_FUTURE_ASSOCIATED_TO_MSG_ID_COMPLETED" warnings
in the log.
I turned on debug and in the log I see following sequence:

-----------------------------------------------------------------
Is this warning really needed?
It looks like a race condition and unnecessary logging.
