> A user reported that the {{AsyncWaitOperator}} does not handle exceptions

> public void test() throws Exception {
> StreamExecutionEnvironment env =
> StreamExecutionEnvironment.getExecutionEnvironment();
> DataStream<Integer> withTimestamps =
> env.fromCollection(Arrays.asList(1,2,3,4,5));
> AsyncDataStream.unorderedWait(withTimestamps,
> (AsyncFunction<Integer, String>) (input, collector) -> {
> if (input == 3){
> collector.collect(new RuntimeException("Test"));
> return;
> }
> collector.collect(Collections.singleton("Ok"));
> }, 10, TimeUnit.MILLISECONDS)
