Request for a better way to handle exceptions thrown from State class's execution methods

[tcascio]

I think it would be nice to have a generic way to handle exceptions thrown from State class's execution methods (like a controller advice in Spring).

Hi @tcascio, @longquanzheng and I were reviewing this ticket and we have some concerns about a feature like this:

• increased learning curve for future users
• hidden "magic"

Are you thinking of something like @NotRetriableException = RuntimeException
