dgü commented on SSHD-1281:
---------------------------
The problem happens in SFTP too in SSH 2.9.0, but not in SSHD 2.8.0.
The example:
{code:java}
URI uri = new URI("sftp://deneme:[email protected]:22";);
try (FileSystem fs = FileSystems.newFileSystem(uri,
Collections.<String, Object>emptyMap())) {
Path sourceFile = Paths.get(new
URI("sftp://deneme:[email protected]:22/C:/Users/dunal/Desktop/sil/sftp/sil1.txt";));
Path targetFile = Paths.get(new
URI("sftp://deneme:[email protected]:22/C:/Users/dunal/Desktop/sil/sftp/sil2.txt";));
Files.copy(sourceFile, targetFile,
StandardCopyOption.REPLACE_EXISTING);
}
{code}
The exception:
