-------------------------------------
A message from Alan Bateman:
Trustin,
I had a mail yesterday from someone that asked me to comment on this issue:
https://issues.apache.org/jira/browse/DIRMINA-379
I don't have a login on that site so I cannot reply but I see you are
"Assignee" so I figured I would mail you.
A long standing issue with the socket adapters is that they aren't synchronized
with the closing of the channel. In order words, if you invoke methods on the
Socket obtained from the socket channel's socket method then it does not throw
an exception to indicate that the socket is closed. The typical error will be
an "Invalid argument" error but it can vary by platform. For Windows Vista it
will typically be an error to say the handle isn't a socket. We have replaced
this code as part of the implementation of NIO2 so it will not be an issue in
the future. I can't say for sure that your issue 379 is the same thing but if
you can duplicate the problem easily then it would be great if you test if the
channel is open or closed by invoking the isOpen method. If its closed that
will explain the issue. If the channel is open then it may be an issue we
haven't seen before, in which case it would be great if you could forward it to
bugs.sun.com.
Thanks,
Alan.
