[SNMP4J] TreeUtils detecting issues with getSubtree results

[Mackay, Scott]

That is good.  I am hoping that the loop and conditions I am checking are the accurate ones to detect this particular issue.
Are the inner checks, isError()==true, getStatus()==TreeEvent.STATUS_REPORT, and finally bind.getOid().equals(SnmpConstants.usmStatsNotInTimeWindows)==true the path to detect a condition like this or is there another combination?  I am afraid I have not seen any material on the website to get to the details as an example.

Hi Scott,
Normally the last entry in the list has the error. Any other case  
would indicate an abnormal behavior of the agent.

Best regards,
Frank
