Resource leak in InputStreamDownload.java

[siddjain]

There is a bug in this code:

@Override
    public void write(HttpServletResponse response) throws IOException {
        writeDetails(response);

        OutputStream out = response.getOutputStream();
        ByteStreams.copy(stream, out);  
    }

the input stream is never disposed.
