>             Project: Flink
>          Issue Type: Bug
>          Components: Table API & SQL

> {code:java}
> Examples:
> KafkaTableSource source = Kafka010JsonTableSource.builder()
> .withSchema(TableSchema.builder()
> .field("sensorId", Types.LONG()) 
> .field("temp", Types.DOUBLE())
> .field("ptime", Types.SQL_TIMESTAMP()).build())
> .withProctimeAttribute("ptime")
> .build(); tableEnv.registerTableSource("flights", source ); {code}
> {{ }}
> {code:java}
> Kafka010JsonTableSource implement the DefinedRowtimeAttributes .
> so when TableSourceUtil call hasRowtimeAttribute(source)to check ,it will call follow code
> /** Returns a list with all rowtime attribute names of the [[TableSource]]. */
> private def getRowtimeAttributes(tableSource: TableSource[_]): Array[String] = {
>   tableSource match {
>     case r: DefinedRowtimeAttributes =>
>       r.getRowtimeAttributeDescriptors.asScala.map(_.getAttributeName).toArray
>     case _ =>
>       Array()
>   }
> }
>  r.getRowtimeAttributeDescriptors will throw NPE because of we use ProctimeAttribute here
> {code}
