Review comment:
I was also thinking about that. But here I want to verify the runtime I got
here is a RichAsyncFunctionRuntimeContext, which is a private inner class of
RichAsyncFunction. So I cannot use isInstanceOf to verify it. Perhaps I could
move the inner class out of RichAsyncFunction and made it accessible by test,
so I can verify the RuntimeContext.

> I can't find any tracking info about the chance to have RichAsyncFunction in

> access open/close methods and the RuntimeContext.

> only, so my question is if there are some blocking issues avoiding this
> feature. [~till.rohrmann]
> If it's possible and nobody already have done it, I can assign the issue to
