Type
object that represents the declared type for this record component. If the declared type of the record component is a parameterized type, the Type
object returned reflects the actual type arguments used in the source code.
If the type of the underlying record component is a type variable or a parameterized type, it is created. Otherwise, it is resolved.

- if the generic record component signature does not conform to the format specified in The Java Virtual Machine Specification
