Aborting an FtpInputStream leads to exceptions (NPE..) with the underlying FTPClient
------------------------------------------------------------------------------------

                 Key: VFS-214
                 URL: https://issues.apache.org/jira/browse/VFS-214
             Project: Commons VFS
          Issue Type: Bug
            Reporter: Gilles Gaillard
            Priority: Trivial


In FtpFileObject.FtpInputStream the method abort has the following implementation:

  client.abort();
  close();

The first call to client.abort() disconnects the client which closes all streams and sockets.
Then 'close' tries to call client.completePendingCommand() therefore resulting in errors like NPE in the FTPClient.
This result in FTP unit tests running with errors.

Calling close first, then client.abort seems to resolve the issue and fix these errors in unit tests.
