    Description

      If the image transfer process receives a client-side error when transferring edit logs, it will throw an exception before it has completely read all of the input from the server-side servlet. Then, the finally clause will throw a new error, since the received length is less than the length given in the header. This masks the client-side exception and makes it look like a network error or a server-side problem.
