> Observed on v2.22.0
> When withMaxReadTime() is used, Beam creates an
> BoundedReadFromUnboundedSource [1]. The ReadFn<T> class in
> BoundedReadFromUnboundedSource which is responsible for reading records from
> source. You can see this class doesnt verify if there is a recoverable
> checkpoint exist. Instead it always creates Reader with checkpointMark set as
> null [2].
