NioBufferedFileInputStream

final class NioBufferedFileInputStream extends InputStream

InputStream implementation which uses direct buffer to read a file to avoid extra copy of data between Java and native memory which happens when using java.io.BufferedInputStream. Unfortunately, this is not something already available in JDK, sun.nio.ch.ChannelInputStream supports reading a file using nio, but does not support buffering.
