Unbounded exponential backoff will sleep a random number of intervals within an exponentially increasing number of intervals. @author elandau

Implementation of {@link BackOff} that increases the back off period for eachretry attempt. When the interval has reached the {@link #setMaxInterval(long) max interval}, it is no longer increased. Stops retrying once the {@link #setMaxElapsedTime(long) max elapsed time} has been reached.

Example: The default interval is {@value #DEFAULT_INITIAL_INTERVAL} ms,the default multiplier is {@value #DEFAULT_MULTIPLIER}, and the default max interval is {@value #DEFAULT_MAX_INTERVAL}. For 10 attempts the sequence will be as follows:

 request#     back off 1              2000 2              3000 3              4500 4              6750 5             10125 6             15187 7             22780 8             30000 9             30000 10             30000

Note that the default max elapsed time is {@link Long#MAX_VALUE}. Use {@link #setMaxElapsedTime(long)} to limit the maximum length of timethat an instance should accumulate before returning {@link BackOffExecution#STOP}. @author Stephane Nicoll @since 4.1
