> When start has not been called on the Readers of CountingSource, the checkpoint may contain a null value which lets the AvroCoder fail with a NullpointerException.
> UnboundedSourceWrapper should not attempt to checkpoint before the readers have been started:
> {quote}getCheckpointMark not be called before \{@link #start\} has been called.{quote}
