L created VFS-559:
---------------------
Summary: FTPClientWrapper is not robust against some failures
Key: VFS-559
URL: https://issues.apache.org/jira/browse/VFS-559
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.0
Reporter: L
The goal of the class is stated in javadoc:
A wrapper to the FTPClient to allow automatic reconnect on connection loss.
A lot of its methods look like :
try
{
do something...
}
catch (final IOException e)
{
disconnect();
try to repeat the operation...
}
Unfortunately disonnect() can fail for the same reason as the original "do
something". In my case it as a "connection reset". So instead of the original
exception I was getting more or less the same exception from
getFtpClient().quit();
So the wrapper did not help at all.
I guess all the disconnect() invocations must also be inside try/catch so that
even if disconnect() throws, the method goes on to the next step: try to
repeat the operation...
