uttamgupta opened a new issue, #717:
URL: https://github.com/apache/mina-sshd/issues/717
### Version
2.14.0
### Bug description
In our environment, few users don't have home folder and it set to /dev/null
. But SshClient tries to read config file and it throws exception.
Although it expects exception NoSuchFileException. see code snippet from
file FileSnapshot.java
`public static FileSnapshot save(Path file, LinkOption... options) throws
IOException {
BasicFileAttributes attributes = null;
Instant now = Instant.now();
try {
attributes = Files.readAttributes(file,
BasicFileAttributes.class, options);
} catch (NoSuchFileException e) {
return NO_FILE;
}
if (attributes == null) {
return NO_FILE;
}
return new FileSnapshot(now, attributes.lastModifiedTime(),
attributes.size(), attributes.fileKey());
}`
### Actual behavior
```
java.nio.file.FileSystemException: /dev/null/.ssh/config: Not a directory

### Expected behavior
I think it should also expect "Not a directory" .
### Relevant log output
```Shell
```
