----------------------------------
Hi [~trohrmann] , I also find the {{SerializedValue.getByteArray()}} is called
in {{AkkaRpcActor}} and {{RemoteRpcInvocation}}. And they both has some
prolematic code to check the length of serializedData by:
{{SerializedValue.getByteArray().length}}.
> Missing null value handling for SerializedValue's getByteArray()
> -----------------------------------------------------------------
>
> Key: FLINK-20580
> URL: https://issues.apache.org/jira/browse/FLINK-20580
> Project: Flink
> Issue Type: Bug
> Components: API / Type Serialization System
> Affects Versions: 1.13.0
> Reporter: Matthias
> Priority: Minor
> Labels: starter
>
> {{SerializedValue}} allows to wrap {{null}} values. Because of this,
> {{SerializedValue.getByteArray()}} might return {{null}} which is not
> properly handled in different locations.
> We should add null handling in these cases and add tests for these cases.
