Now the `startTime` in `TaskResultAggregator` is a transient `Long` that is initialized when the object is created, not in the `open` method. When the job recovers from a failure, it becomes null and causes a NullPointerException (NPE) when `processWatermark` is call before `processElement1` constructing the required `long` for `TaskResult`. This PR aims to change the initialization of `startTime` to the `open` method. If `startTime` is 0, the `TaskResult` will not be propagated downstream; instead, it will rely on the advancement of the watermark to reach downstream operators. -- This is an automated message from the Apache Git Service.
