Mission critical, large-scale online production systems need to make progress without downtime despite some issues. Some program exceptions tend to be transient, in which case the corresponding task can be retried. Examples include network connection errors, timeouts, etc. These are called recoverable exceptions. The isIgnoringRecoverableExceptions should only be enabled if an exception misclassification bug has been identified.
