---------------------
Summary: FTPClientWrapper hides important error information
Key: VFS-581
URL: https://issues.apache.org/jira/browse/VFS-581
Project: Commons VFS
Issue Type: Bug
Affects Versions: Nightly Builds, 2.1
Reporter: L
One place where FTPClientWrapper hides errors is method listFilesInDirectory().
1. Lines 163-167: After performing getFtpClient().listFiles(relPath); the code
checks for a positive FTP reply.
2. If the reply was negative, the code assumes the negative reply has to do
with VFS-307 as stated in the comments. This is not always the case, there
might be other reasons why the operation might have failed. In my case it was
an FTPS connection where the server required an encrypted data channel and the
client did was not properly configured.
3. Line 182: getFtpClient().listFiles();. This time without even looking at the
FTP reply string. In my case it was the same error as above. As a result my
client got an empty as if the remote directory did not have any files, while
the real error reason was nowhere to see.
