fioan89 opened a new issue, #401:
URL: https://github.com/apache/mina-sshd/issues/401
### Version
2.10.0
### Bug description
When using the SCP client to upload a file to a remote location that does
not exist a `WindowClosedException` is raised instead of a more user friendly
SCP exception detailing the reason of why the upload/download failed.
The snippet of code below raises a `WindowClosedException` exception when
`/remote/path/that/does/not/exist` doesn't exist.
```
val session = sshClient.connect(
username,
hostname,
port
).verify(5000).session
session.auth().await(5000)
scpClient = ScpClientCreator.instance().createScpClient(session)
scpClient.upload("/local/path/file_name",
"/remote/path/that/does/not/exist/file_name", options)
```
### Actual behavior
```
e = {WindowClosedException@37364}
"org.apache.sshd.common.channel.WindowClosedException: Already closed:
RemoteWindow[client](ChannelExec[id=0,
recipient=0]-ClientSessionImpl[ifaur@localhost/127.0.0.1:2222])"

### Expected behavior
a `SCPException` or even a basic `IOException` with a more relevant message:
- destination "/remote/path/that/does/not/exist/file_name" does not exist or
could not be created
- "/remote/path/that/does/not/exist/file_name" no such file or directory
### Relevant log output
