> when review PR#16970。 I find function `ContextualRecord#hashCode()、ProcessorRecordContext#hashCode() ` be deprecated because they have a mutable attribute, which will cause the hashCode to change。 
> I don't think that hashCode should be discarded just because it is mutable. HashCode is a very important property of an object. It just shouldn't be used for hash addressing, like ArayList
