--------------------------------
    Summary: Error executing processElement when inheriting from 
AbstractAsyncStateStreamOperator  (was: Error in calling processElement for 
AbstractAsynchronous StateStreamOperator)

>             Project: Flink
>          Issue Type: Bug
>          Components: Table SQL / Runtime
>    Affects Versions: 2.0.0
>            Reporter: Wang Qilong
>            Priority: Major

> When I created the AbstractAsynchronous StateMapBundleOperator and inherited 
> it from the AbstractAsynchronous StateStreamOperator, there was an error in 
> the data passed into the element by the processElement of the 
> AbstractAsynchronous StateMapBundleOperator itself
> The inheritance relationship between asynchronous synchronization and two 
> classes is:
> AbstractMapBundleOperator->AbstractStreamOperator
> AbstractAsyncStateMapBundleOperator->AbstractAsyncStateStreamOperator->AbstractStreamOperator
> The reason for creating this class is to enable KeyedMapBundleOperator to 
> support asynchronous running capability
> Example of incorrect information: For example, the original data format was:
> val data = new mutable.MutableList[(String, Long)]
> data.+=(("x", 1L))
> data.+=(("x", 2L))
> data.+=(("x", 3L))
> data.+=(("y", 1L))
> data.+=(("y", 2L))
> data.+=(("z", 3L))
> So the result of data transmission becomes:
> val data = new mutable.MutableList[(String, Long)]
> data.+=(("x", 1L))
> data.+=(("x", 2L))
> data.+=(("x", 3L))
> data.+=(("x", 1L))
> data.+=(("x", 2L))
> data.+=(("x", 3L))
> How to reproduce:
> Run testOverloadedAccumulator in SQL/AggregateITCase.jva in [1]
