> [https://github.com/apache/flink/blob/master/flink-table/flink-table-runtime/src/test/java/org/apache/flink/table/runtime/operators/over/NonTimeRangeUnboundedPrecedingFunctionTest.java#L55] didn't catch it because `sum` in [https://github.com/apache/flink/blob/master/flink-table/flink-table-runtime/src/test/java/org/apache/flink/table/runtime/operators/over/SumAggsHandleFunction.java#L30] is long. It will fail with NPE if change it `Long`
