D- the type of generic declaration that declared the underlying type variable.
public interface TypeVariable<D extends GenericDeclaration> extends Type
Multiple objects may be instantiated at run-time to represent a given type variable. Even though a type variable is created only once, this does not imply any requirement to cache instances representing the type variable. However, all instances representing a type variable must be equal() to each other. As a consequence, users of type variables must not rely on the identity of instances of classes implementing this interface.
