SFTPFileNotFoundException on SSHSFTPClient.close

[Tom Quarendon]

I'm uploading a file using SSH2SFTPClient by calling
open
writeFully
close

The upload appears to be successul in that the file appears and I can 
open it successfully. However the close call throws an 
SFTPFileNotFoundException :

       [ssh] com.mindbright.ssh2.SSH2SFTP$SFTPNoSuchFileException
       [ssh]     at com.mindbright.ssh2.SSH2SFTPClient.checkType(Unknown 
Source)
       [ssh]     at 
com.mindbright.ssh2.SSH2SFTPClient.transmitExpectReply(Unknow
n Source)
       [ssh]     at com.mindbright.ssh2.SSH2SFTPClient.close(Unknown Source)

I'm ignoring this exception, as it appears that it all works anyway. 
Should I be calling close in this way?
Cheers.
