code: @Override
      public void handleException(ProcessingLibraryException exception) {
          ProgressStatus status = exception.getStatus();
          ProgressState state = status.getProgressState();
          ProgressInfo info = status.getProgressInfo();
          logger.error(String.format("Exception. Progress State: %s. Progress Information: %s.", state, info));
      }
docs: Exception handler that simply log progress state and progress information.
