   * The first five lines of the journal form its header. They are the constant string
   * "libcore.io.DiskLruCache", the disk cache's version, the application's version, the value
   * count, and a blank line.
   *
   * Each of the subsequent lines in the file is a record of the state of a cache entry. Each line
   * contains space-separated values: a state, a key, and optional state-specific values.
