> {{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.
