   * How this works is best explained with an example:
   *
   * For a RateLimiter that produces 1 token per second, every second that goes by with the
   * RateLimiter being unused, we increase storedPermits by 1. Say we leave the RateLimiter unused

        // The third parameter is the size of the output string in characters
        // size = number of hex characters to output
        // Each byte produces 2 hex characters

        // Test basic conversion (srcIndex is ignored in the implementation)
        byte[] data1 = { 0x00, 0x01, 0x02, 0x03 };
        assertEquals("00", Hexdump.toHexString(data1, 0, 2)); // 2 chars = 1 byte

     * AbstractFuture.executeListener to do so, since that method would have the ability to continue
     * to execute other listeners.
     *
     * What about RuntimeException? If there is a bug in set()/setValue() that produces one, it will
     * propagate, too, but only as far as AbstractFuture.executeListener, which will catch and log
     * it.
