TCP connection close by server leads to client crash

[GoogleCodeExporter]

What steps will reproduce the problem?

That is not easy. The problem occurs occationally. For that I have attached
the exception stacktrace below.

Maybe the following could work:

1. Use openfire server and pollute it with as many connections that it can
handle.
2. Openfire will drop further connections.

What is the expected output? What do you see instead?

What happens: jabber-net library throws unhandeled exception leading to
application crash
Expected: Exception is handled and connection establishment fails gracefully

What version of the product are you using? On what operating system?

jabber-net.dll 2.0.0.613 on Windows XP SP3. I had a look at the svn diffs.
There seam to be no changes regarding this issue since 613.

Please provide any additional information below.

Here is another one occuring at the same place in the code that is very easy to
reproduce.

Steps to reproduce:
1. Use openfire as server with SSL on 5223
2. Connect using SSL and wrong port 5222 (5223 works correctly of course)
3. jabber-net throws unhandled exception shown below

transport
stream.
