> Note sure if this code is even being used, but it implements a copy routing utilizing
a 2K buffer.  Modern JVM uses 8K, but 4K should be minimum.  Also, there are libraries for
this stuff.
> {code:java|title=FileUtil.java}
>     int count;
>     byte data[] = new byte[2048];
>     try (BufferedOutputStream outputStream = new BufferedOutputStream(
>         new FileOutputStream(outputFile));) {
>       while ((count = tis.read(data)) != -1) {
>         outputStream.write(data, 0, count);
>       }
>       outputStream.flush();
>     }
> {code}
> I also fixed a couple of check-style warnings.
