             Project: MINA SSHD
          Issue Type: Question
    Affects Versions: 2.8.0

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!
