I don't think so. The call to super.close() executes the following code, 
which is declared in ImageInputStreamImpl (there is no close() method in 

     public void close() throws IOException {
         isClosed = true;

There is apparently nothing else in the call to super.close(). 
Furthermore, other implementations like FileImageOutputStream also 
perform the same super.close() call first.
