Description

FileAccess.Random#read currently uses RandomAccessFile#readFully() to read a segment from a tar file. That method requires a byte array and does not work with ByteBuffer instances directly. To make this method more universal (e.g. to work also for off heap byte buffers) I would like to change it to use FileChannel#read instead.
