> In FLINK-25990 , 
> Add a method "DataStream<RowData> produceDataStream(ProviderContext 
> providerContext, StreamExecutionEnvironment execEnv)" in 
> DataStreamScanProvider.
> But this method has no default implementation, this is not compatible when 
> users upgrade to 1.15 from 1.14.
> This method should be:
> {code:java}
>     default DataStream<RowData> produceDataStream(
>             ProviderContext providerContext, StreamExecutionEnvironment 
> execEnv) {
>         return produceDataStream(execEnv);
>     }
> {code}
