             Summary: TFTPClient assumes that lastBlock == 0 only once
                 Key: NET-613
                 URL: https://issues.apache.org/jira/browse/NET-613
             Project: Commons Net
          Issue Type: Bug
    Affects Versions: 3.5
            Reporter: Sebb


TFTPClient assumes that lastBlock == 0 only once.

However, that is not the case.
It may become 0 if the block count wraps round or the server sends a packet 
with it set to 0.
