> When the MapGetExecutor is init by the key null, the property of
> MapGetExecutor will be null.
> If the MapGetExecutor is cached and the key is changed (like map[index]),
> there will throw an NPE.
> I think the intention for the condition is to compare the class
> compatibility, so I add the NPE check here.
