```scala @ApiMayChange def aggregateWithBoundary[Agg, Emit](allocate: java.util.function.Supplier[Agg], aggregate: function.Function2[Agg, Out, Pair[Agg, Boolean]], harvest: function.Function[Agg, Emit], emitOnTimer: Pair[java.util.function.Predicate[Agg], java.time.Duration]): javadsl.Source[Emit, Mat] ``` I think it should be ```scala @ApiMayChange def aggregateWithBoundary[Agg, Emit](allocate: java.util.function.Supplier[Agg], aggregate: function.Function2[Agg, Out, Pair[Agg, Boolean]], harvest: function.Function[Agg, Emit], emitOnTimer: Optional[java.util.function.Predicate[Agg], java.time.Duration]]): javadsl.Source[Emit, Mat] ``` The `emitOnTimer` should be an `Optional`. The API is marked as `@ApiMayChange` -- This is an automated message from the Apache Git Service.
