Error retrieving stream from servlet: java.io.IOException: missing CR

i'm trying to get back a byte[] array from a servlet and getting an error.  the byte array is being written to a stream in the doPost method via this:

      MultipartRequest multiRequest = createMultiRequest(request);
      
            String accountID = getParameterFromMultipart(multiRequest, "accountID");
            String recordUID = getParameterFromMultipart(multiRequest, "recordUID");
            
            response.setContentType("application/x-download");
            response.setHeader("Content-Disposition", "attachment; filename=" + recordUID + ".data");
            
            BufferedOutputStream out = new BufferedOutputStream(response.getOutputStream());
                  
            try
            {
                  byte[] bytes = //do stuff here to get the bytes
                  out.write(bytes);
                  out.close();
            }

and then these bytes are being read back in here:


ByteArrayOutputStream bais = new ByteArrayOutputStream(chunkSize);

            int bytesRead = 0;
            bytesRead = stream.read(byteBuffer);

            while (bytesRead != -1) {
                  bais.write(byteBuffer, 0, bytesRead);
                  bytesRead = stream.read(byteBuffer);
            }
            byte[] readRecordBytes = bais.toByteArray();
            bais.close();

where the stream is retrieve from

BufferedInputStream stream = new BufferedInputStream(
                              retrieveRequest.post());

At some pont in the loop of reading teh bytes, stream.read(byteBuffer) throws an error:  java.io.IOException: missing CR.  Am I not allowed to just write bytes to the stream the way I am on the servlet?
