Subject [jira] Commented: (NET-278) FTPClient.disconnect() shouldn't throw IOException
Date Tue, 12 May 2009 21:49:45 GMT


Sebb commented on NET-278:

It may be important to know that the disconnect() failed, as that usually indicates some kind
of problem with the session.

This is similar to calling close() on a file, which may also throw an IOException.

In both cases, the correct action may be to log an error, which you can't do if no Exception
is thrown.

> FTPClient.disconnect() shouldn't throw IOExceptions because it is typically placed in
a finally block and it doesn't make much sense to

> What is the purpose of such an exception if nobody can use it? There's nothing we can
do if the client couldn't disconnect... You always usa a catch block with a /*do nothing*/
in your samples, so I think it's only an elegant thing to have a try block in a finally block...
