[jcifs] JCIFS error, Oracle VM Issue, or Novell Again?

1) Try your code against NT 4 if you can just to rule out a client side
issue.
2) Try the latest version of jCIFS if you are not already. We just fixed an
issue with Novell.
5) Try Suns JRE. You're using Oracle's VM which is known to have an issue with jCIFS:
http://lists.samba.org/pipermail/jcifs/2002-May/002192.html
This should determine if the issue is with Oracle's VM, Novell server, or jCIFS. The socket is
just being blatantly closed after that write, thus the "Unexpected EOF". The VM SocketImpl
could be choking on the larger write or Novell might be dying on an error it's not equipped to
respond to.
