InputStreamMonitor.updateBody throwing OutOfMemoryError for writing of InputStream in FileOutputStream

I'm writing file from network (using HttpURLConnection) to my device with code:

                BufferedInputStream bis = new BufferedInputStream(c.getInputStream());
                byte[] buffer = new byte[1024];
                int count = 0;
                long downloadedBytes = 0;
                while ((count = bis.read(buffer)) != -1) {
                    fos.write(buffer, 0, count);
                    downloadedBytes += count;
                }
                fos.close();
                bis.close();

When downloaded file is big (19MB), splunk throws RuntimeException:

I tried Mint.addURLToBlackList - for domain name (domain.com) and for file (domain.com/file.ext), but doesn't work. I don't want to disable network monitoring. Is there any way, to download large file without this error?
