Description
Hi!
We define our Spring MVC APIs with @RequestParam Optional<Type> something.
It looks like Feign doesn't handle it well and uses "toString()" version so that Spring fails to convert String -> Optional

Research direction
Start by tracing Feign's request-parameter expansion and how Optional values are converted when calling a Spring MVC API. Reproduce the issue with @RequestParam Optional; done means conditional expansion produces a value Spring can convert instead of the Optional object's toString() form.
