ResolvableType forClass fails when a type in the generic signature isn't present

[wilkinsona]

Via spring-projects/spring-boot#21431 and somewhat similar to #25050, it appears that ResolvableType needs to handle a TypeNotPresentException being thrown when it queries generics. Here's the failure from the Boot issue:
