[jcifs] Connection in error

[Michael B Allen]

This just means pretty much what it looks like. The client tried to open
a socket and it never got a response. Older clients did have strange
behavior when this happend where the transport would get in a bad state. I
believe the behavior now is if multiple threads are trying to connect on
the same transport and the current one chokes (e.g. Connection timeout)
the next thread gets a "Connection in error" and resets the state to
0. The next thread should be able to succeed (unless the server still
isn't responding in which case you'll get the same error and the cycle
will continue). So when the server becomes available again the client
should recover depending on how dillegent your retry code is.

Also, the difference between 1.2.6 and 1.2.9 is only good. There were no
radical changes that should affect the behavior of your application. It
would be pretty safe to upgrade.

But check the REAMDE.txt to see what those changes were.
