> When a password is required to connect the FTP server, the implementation of method login
in class FTPClient ends with:
>   return FTPReply.isPositiveCompletion(pass(password))
> which returns false for any code >= 300.
> However, some servers send a code 451 before returning the code 530 (NOT_LOGGED_IN).
Ignoring this addtional answer,
> leads to desynch the client with the server, hence leading to unexpected behaviors in
next exchanges.
> Threfore i propose to replace the above code in the end of the method with:
>       _replyCode = p_Client.pass(p_Password);
>       boolean result = FTPReply.isPositiveCompletion(_replyCode);
>       if (!result && _replyCode==FTPReply.ACTION_ABORTED){
>         try {
>           _replyCode = p_Client.getReply();
>         } catch (Exception e){
>           e.printStackTrace();
>         }
>       }
>       return result;
