Issue with `equals(…)`/`hashCode()` for `ResolvableType.forRawClass(…)`

[odrotbohm]

ResolvableType.forRawClass(…) returns an anonymous subclass of ResolvableType that alters its behavior but does not override equals(…)/hashCode() so that instances created through that method are considered the same as ones created via forClass(…) despite different behavior when trying to resolve generics. This fundamentally breaks the ability to use ResolvableType instances that are potentially created in both ways as map or cache keys.
