> When users override {{snapshoteState}}, they might include logic there which is crucial for the correctness of their application, e.g. finalizing a transaction and buffering the results of that transaction, or flushing events to an external store. Exceptions occurring should lead to failing the job.
> Currently, users must make sure to throw a {{Throwable}} because any {{Exception}} will be caught by the task and reported as checkpointing error, when it could be an application error.
> It would be helpful to update the documentation and introduce a special exception that can be thrown for job-related failures, e.g. {{ApplicationError}} or similar.
