---------------------------
Hello!
Thank you for the response. I can not use _try-finally_ block either. My main
logic is is not between _try_ blocks. Anyway, this is not the question even if
there can be other way.
My question was about asynchronous nature of SSHD and race conditions between
SSHD and client applications.
I expected something like listener to be notified to be sure about the state of
SSHD calls. So that, I must see the state as if it is synchronous.
I will work on your listener recommendation.
Thanks!

> Hello!
> I want to release client connection resources after connection timeout occurs
> ?
> This is the code:
> {code:java}
> ConnectFuture connectFuture = sshClient.connect(uri.toString());
> try {
> //connectFuture.isConnected() returns false
> connectFuture.verify(timeout);
> } catch (IOException e) {
> //connectFuture.isConnected() returns true
> connectFuture.cancel();
> //connectFuture.isCanceled() returns false
> //connectFuture.isConnected() returns true
> throw e;
> }
> {code}
> I guess there is a race condition between client connection and
> {{ConnectFuture#isConnected()}}.
> For example, this code may be wrong:
> {code:java}
> if (!connectFuture.isConnected()) {
> //connectFuture.isConnected() may return true
> }
> {code}
> In my case, session is connected after timeout.
> How can I be sure that client is still not connected and release its
> resources after connection timeout occurs ?
> Thanks in advance!
